Groovy Libraries classpath container

Issues with javadoc and sources attchment have been fixed for jars within the Groovy Libraries classpath container. Javadoc links for the built-in Groovy and Ivy libraries have been fixed so included javadoc is used. Sources and/or Javadoc jars will be properly attached to main jars for ${user.home}/.groovy/lib items:

Groovy Editor

Code Minings

Added in Eclipse 4.8 (Photon), Editor Code Minings (aka Inline Annotations) is the answer to VS Code's CodeLens. This feature has been moved from prototype status to fully available and configurable. Support for displaying references, implementations and parameter names is available. Additional Code Minings can be added using the standard Eclipse API.

Global AST Transforms

Sources opened in the Groovy Editor will now have global transforms applied (except Spock). Previously, only Grab and AstBuilder were executed by default and a system property could be set to include others. Now, like local transforms, global transforms are applied to give the most accurate representation of the AST.

The Spock transform is still excluded until some issues with the value recorder AST re-writes in the expect block can be addressed.

Outline View

Removing a field (or other element) using the Outline View no longer causes issues in the Groovy Editor when using Windows line endings (\r\n).

Call Hierarchy and Find Occurrences

Call Hierarchy (Ctrl+Alt+H), Find References (Ctrl+Shift+G), etc. for Groovy properties produce more accurate matches for bean-style (idiomatic), direct-field and accessor-method uses under static compilation. Previously some of these kinds of references were marked as potential matches, which can be confusing and hampers refactorings like rename.

class Pogo {
  Number number
}
class Groovy {
  @groovy.transform.CompileStatic
  void meth(Pogo pogo) {
    pogo.number
    pogo.@number
    pogo.number = 0
    pogo.getNumber()
    pogo.setNumber(42)
  }
}
public class Java {
  public void meth(Pogo pogo) {
    Number n = pogo.getNumber();
    pogo.setNumber(42);
  }
}

Java Interoperability / Joint Compilation

Compatibility has been improved for annotation attribute default and static final field initial values.

  • handle default initializers (primitive with no value expression)
  • handle character literals/casts
  • handle negative number literals
interface Groovy {
  int ZERO
  char SPACE = ' '
  long LOWER_BOUND = -1
}

Type Inferencing and Syntax Highlighting

Pre-release Groovy compiler fixes

Support for new version of Eclipse

  • Eclipse 4.12 (2019-06)

Support for Java 12

As of Eclipse 4.12, Java 12 is fully supported within the IDE. It can be combined with any supported version of Groovy. Modulepath entries are not yet supported for Groovy sources; classpath entries work as expected.

Run As > Groovy Script - config script handling

Two paths exist when running a Groovy Script from a project that supplies a compiler configuration script:

  1. If script is part of project's classpath (in source folder and does not match a script filter), config script is applied
  2. If script is not part of project's classpath (not in source folder or matches a script filter), config script is not applied

This matches the general handling of Groovy scripts with respect to compiler configuration within the project. So, for example, if you added an import in your config script and your script is expecting this import to resolve a referenced type, the config script is applied at runtime and the script should execute properly.

Content Assist and Quick Fixes

Completing the type on a new field or property declaration has been improved.

class Pogo {
  String foo
  Tree|
}

Applying one of the type completion proposals at | now respects the user's import/qualifer preferences.

If "Tree" is preceded by a modifier and a "Tree" type proposal is applied, there is still an open issue: https://github.com/groovy/groovy-eclipse/issues/873

Call Hierarchy and Find Occurrences

Implicit-this (no object expression) field references in sources with @CompileStatic are now resolved correctly.

@CompileStatic
class Pogo {
  boolean flag
  Pogo(Pogo that) {
    flag = that.flag // 2 occurrences
  }
  void setFlag(boolean value) {
    if (condition()) {
      flag = false // 1 occurrence
    } else {
      flag = value // 1 occurrence
    }
  }
  private boolean condition() { ... }
}

When searching for references of the field flag, only that.flag was producing a match within the class.

Type Inferencing and Syntax Highlighting

  • Repeated annotations
  • Constructor declarations
  • Deprecated this/super constructor calls
  • Overloaded methods and property expression argument(s)
  • Static final property accessed from outside of declaring class
  • Static reference to instance method in Groovy 3 (Parrot Parser enabled)

Syntax Highlighting of type references

As seen in the Java editor, the Groovy editor has been enhanced to provide separate preferences for highlighting:

  • Classes
  • Abstract classes
  • Interfaces
  • Annotations

Color/style fallbacks for disabled preferences

If a syntax highlighting group on the left is disabled, it will fall back to the designated group on the right. These match the Java editor's behavior and should increase flexibility when setting up color/style profiles.

  • Abstract class -> class
  • Method declaration -> method
  • Static method invocation -> method
  • Static final field -> static field -> field
  • Parameter declaration -> local variable declaration

In addition, any disabled color/style group that does not have an enabled fall back will properly fall back on Other (the default non-brace, non-operator color/style).

NOTE: Unlike the Java editor, the color choice for Deprecated is ignored by the Groovy editor. Only the style (strikethrough by default) is applied.

Reference to Groovy property from Java source

In the Java editor, code hover (F2) and code select (F3 or Ctrl+click) over getString used to refer to class Pogo and not property string, which made quick determination of expression type a pain.

Now the reference is resolved as it is within the Groovy editor and navigation works as expected:

Error ranges for annotations

An off-by-one error was fixed for source elements on the first line of a source unit. And the leading @ is now included in the source range of annotations, which matches the Java editor.

Support for new versions of Groovy

  • Groovy 2.5.5
  • Groovy 2.4.16

Support for new version of Eclipse

  • Eclipse 4.10 (2018-12)

Support for Java 11

As of Eclipse 4.10, Java 11 is fully supported within the IDE. It can be combined with any supported version of Groovy. Modulepath entries are not yet supported for Groovy sources; classpath entries work as expected. Lambdas, method references and var keyword support is available in Groovy 2.6+.

New Type Wizard

JDT has separate wizards for creating classes, interfaces, etc. If GDT followed this pattern, there would be quite a few items in the New context menu. Instead, the New Groovy Class wizard has been enhanced to support selection of other Groovy archetypes. This reduces clutter and makes room for additional Groovy-specific controls.

Closure delegate and owner members

When engaging content assist (Ctrl+Space) within a closure, delegate and owner property completions are proposed. In case of a conflicting name, a qualifier may be added depending on the closure's resolve strategy. In this case, DefaultGroovyMethods.with is defined with a strategy of DELEGATE_FIRST, so delegate properties can be used unqualified, but owner properties may require a qualifier.

public static <T,U> T with(
    @DelegatesTo.Target("self") U self,
    @DelegatesTo(target="self", strategy=Closure.DELEGATE_FIRST)
    @ClosureParams(FirstParam.class) Closure<T> closure)

Support for new version of Eclipse

  • Eclipse 4.9 (2018-09)

Support for Java 11

Eclipse 4.9 does have a patch available that adds Java 11 support. However, since it patches some of the same bundles that Greclipse does, both cannot be applied together. Therefore, Groovy and Java 11 support together will have to wait until Eclipse 4.10 (2018-12) is available.

Problem marker decorations in Project Explorer

Problem marker label decorations were missing for compilation unit nodes (Groovy sources) in the Project Explorer. This has been fixed.

Support for Eclipse Dark Theme

Syntax colors were updated or inherited from Java to make the Dark Theme in the Groovy Editor look and feel like the Java Editor does. Also, the Groovy Event Console colors were updated to show better contrast in Dark Theme mode.

editor colors

editor color prefs

Keyword color prefs were reorganized so def, var and void are highlighted the same as primive type keywords. A separate preference was added for assert, as this might be a keyword you want to highlight differently from the others. Clicking the "Copy Java Color Preferences" properly copies the bold preferences, which are typically off for Dark Theme and on for Light Theme.

Archives of these update sites are also available:

3.0.0

Greclipse 3.0.0 was released on August 2nd 2018.

New and Noteworthy

Support for new versions of Groovy

  • Groovy 2.6a4 new
  • Groovy 2.5.1
  • Groovy 2.4.15

Java 8 is the new minimum supported runtime. Support for Groovy 1.8 through 2.3 has been dropped.

The new Parrot Parser is part of Groovy 2.6+; it can be enabled in 2.6 by setting the groovy.antlr4 system property to true. Error recovery is not yet implemented in the new parser, so edited sources may generate more errors than usual and features like content assist may fail on incomplete expressions.

Support for Ant, Groovy Shell and Groovy Console

Groovy 2.5+ has replaced the monolithic groovy-all jar with a modular approach. This has forced the hand of GDT a bit; built-in support for Ant, Groovy Shell and Groovy Console have taken a bit of a step back. Support remains unchanged if the Groovy 2.4 compiler is used. Otherwise, the required libraries must be supplied on the project classpath. This can be accomplished using Ivy/Maven/Gradle, ~/.groovy/lib or by other means.

Support for new versions of Eclipse

  • Eclipse Photon (4.8.0)
  • Eclipse Oxygen (4.7.3a)

Support for Eclipse 3.7 through 4.6 has been dropped.

Support for Java 10

As of Eclipse Oxygen SR3a and Photon, Java 10 is fully supported within the IDE. It can be combined with any supported version of Groovy. Modulepath entries are not yet supported for Groovy sources; classpath entries work as expected. var keyword support is coming in Groovy 3.

Support for test sources classpath attributes in Photon

Within the Groovy Libraries classpath container, the groovy-test jar from Groovy 2.5+ is marked as "Visible only for test sources". Maven support (m2e) marks src/test/groovy as "Contains test sources".

test sources

The test sources feature offers an interesting opportunity for Groovy AST transforms, extension methods, etc. -- since a two-stage build process now exists within a single project. In the past, if you wanted to create and use AST transforms, it was recommended to use 2 separate projects. In Eclipse Photon, AST transforms could be defined in a non-test source folder and applied in a test source folder of the same project.

Move "Groovy Type Checking" submenu items to "Groovy" submenu

The project context menu has been consolidated, reorganized and updated.

Groovy submenu

In previous releases, the two separate submenus looked like this:

Groovy submenu (old)

Groovy Type Checking submenu (old)

Improvements to Compiler Configuration support

Compiler config script is no longer applied to project resources outside of source folders as well as non-compiled sources (see Groovy > Compiler > Groovy Script Folders). By default, this means any *.dsld and *.gradle scripts will not have the project's config script applied. And it should mean the config script is not applied to itself any longer, making editing of the script much easier. Content Assist and Organize Imports also show improved support for the addition of imports through compiler configuration.

Improvements to Debugger perspective

Several usability improvements have been made for debugging. Class creation breakpoints and field read/write watchpoints have been implemented. Breakpoints can be set for Groovy classes in the Class File Viewer. Method enter/exit breakpoints have been fixed. Debug commands Run to Line (Ctrl+R) and Step into Selection (Ctrl+F5) have been fixed.

Breakpoint types

Improvements to code completion of constructors and methods

Each of the Groovy content assist preferences and the most popular/relevant Java content assist preferences have been tried in combination to ensure support in the Groovy editor is on par with the JDT. The two-state preference "Use guessed arguments for method calls" has been replaced by three-state preference "Fill method arguments and show guessed arguments" provided by JDT. A convenient link has been added to the Groovy > Editor > Content Assist preference page to get to Java's Content Assist preferences.

Constructors can now be completed with or without argument insertion or guessing. Necessary import statements or qualifiers are inserted. And anonymous inner classes can be started quickly by triggering a constructor proposal with {. Methods that have a SAM type for their last parameter can be completed with a Closure literal that includes parameters matching the SAM signature by triggering a proposal with {. Named argument completions do not include trailing ", " any more. The tables below summarize Java and Groovy behavior with different preference and triggering combinations.

Completions for construtors

Completions for sort method

Completions for sort method

Improvements to code completion of groovy.lang.Closure parameters

Methods with a trailing closure received a code completion boost as well. In more cases, a closure literal is inserted in idiomatic fashion -- "Place trailing closure arguments after closing parenthesis" is now on by default -- to encourage Groovy coding practices. The "it" parameter has been removed and replaced with smarter cursor positioning and selection, saving keystrokes and supporting the builder pattern.

Completions for collect method

Completions for collect method

Improvements to groovy.lang.DelegatesTo and groovy.transform.stc.ClosureParams support

Support for @DelegatesTo(type='pack.Type') was completed. All forms of this annotation should work properly now.

Completions for DelegatesTo annotation

Support for @ClosureParams(value=SomeHint, options=[...]) has been added. The conflictResolutionStrategy attribute is not yet supported.

Completions for ClosureParams annotation

Completions for ClosureParams annotation

Improvements to Extension Method (aka DGM) discovery

In conjunction with the changes to use @DelegatesTo and @ClosureParams to replace static lists with runtime discovery of type information, Default Groovy Methods (DGMs) are now being discovered from each project's classpath. This allows changes to DGMs between Groovy versions to be seen and leveraged. And third-party DGMs now have first-class support in content assist and type inferencing.

Improvements to DSLDs for built-in AST transforms

DSLD suggestions for NamedVariant AST transform

DSLD suggestions for Newify AST transform

Improvements to type inferencing and semantic highlighting

Conditional or terminal blocks with assignments

def m1(def x) {
  def cl = { ->
    x = 1
  }
  x // typeof(x) == Object because Closure is not executed
}
def m2(def x) {
  if (predicate()) {
    x = 1
    return 0
   }
  x // typeof(x) == Object because conditional block does not share path here
}
def m3(def x) {
  if (x instanceof CharSequence) {
    x = Integer.valueOf(x) // typeof(x) == CharSequence
  }
  x // typeof(x) == LUB(Object,Integer)
}
def m4(def x) {
  if (predicate()) {
    x = ''
  } else {
    x = new StringBuffer()
  }
  x // typeof(x) == LUB(String,StringBuffer)
}

Methods from java.lang.Class and java.lang.Object

Method toString was inferencing as Class.toString() in:

String[] arr = ...
def str = Arrays.toString(arr)

Method getMethod was showing as unknown (underlined) in:

def m = String.getMethod('toLowerCase')

Property superclass was showing as unknown (underlined) even though hover shows javadoc for Class.getSuperclass in:

Class clazz = String
def parent = clazz.superclass

Method call Chars.equals was showing as unknown (underlined) and hover showed javadoc for Object.equals in:

class Chars {
  static boolean equals(char[] a, char[] b) {
  }
  static void main(char[] x, char[] y) {
    if (Chars.equals(x, y)) {
    }
  }
}

SAM types and groovy.lang.Closure literals

SAM types in assignments, coercions and method parameters can be used to determine closure parameter types.

@FunctionalInterface
interface Sam {
  int meth(int a, Long b, java.util.regex.Pattern c);
}

def util(Sam s) {}

// for each: typeof(a) == int, typeof(b) == Long, typeof(c) == Pattern
util { a, b, c -> ... }
Sam type = { a, b, c -> ... }
def type = { a, b, c -> ... } as Sam

Return type from groovy.lang.Closure

The type of arr is dependent on the return type of the closure expression. length, group, and matches were showing as unknown (underlined) in:

Matcher[] meth() {}
def arr = with {
  return meth()
}
arr.length
arr[0].group(0)
arr[0].matches()

Traditional varargs and pseudo-varargs (last param is array) methods

Variadic method call with multiple overloads was showing as first overload, not best match in:

Arrays.sort() // sort(Object[])
Arrays.sort(new Object()) // sort(Object[])

Content assist for array length

Implicit "length" field for arrays is available as a code completion and correctly inferences as type int.

Content assist for inner types and enum constants

Content assist for inner classes and enum constants has been improved, including discovery with or without outer-class qualifiers. Code completion includes necessary imports or qualifiers depending on content assist preference.

Content assist for catch and throws clauses

Throwable types received a relevance boost for content assist within catch and throws clauses.

Content assist for assignment expressions

Content assist for non-declaration assignment expressions has been improved; parser error recovery has been added. This includes the combined operation assignments like +=, &=, etc. An assignment like foo = | or foo += | now supports correct code completion proposals.

Content assist for ternary operator expressions

Content assist for ternary operator expressions (? :) has been improved to allow completion proposals for def str = condition ? String.val|. Previously this would have caused an unrecoverable parser error, preventing content assist proposals.

Update Sites

Use one of the following update sites depending on your version of Eclipse:

Archives of these update sites are also available:

2.9.2

Greclipse 2.9.2 was released on January 4th 2018.

New and Noteworthy

Support for new versions of Groovy

  • Groovy 2.5.0 new
  • Groovy 2.4.13 new
  • Groovy 2.3.11
  • Groovy 2.2.2
  • Groovy 2.1.9
  • Groovy 2.0.8
  • Groovy 1.8.9

InvokeDynamic flavor included starting with 2.5. Package exports in bundle manifests have been corrected. Several past fixes have been backported to all supported runtimes. Source jars for embedded BSF and Ivy jars have been added where missing and the linkages are made properly so Eclipse sees them.

Support for new versions of Eclipse

  • Eclipse Photon (4.8) pending
  • Eclipse Oxygen (4.7)
  • Eclipse Neon (4.6)
  • Eclipse Mars (4.5)

All other supported versions were patched up to the most recent state of their respective maintenance branches.

Support for Java 9 and JUnit 5

As of Eclipse Oxygen SR1a and Photon M3, Java 9 and JUnit 5 are fully supported within the IDE. Either can be combined with any supported version of Groovy.

All plug-in tests migrated to JUnit 4

Test cases can be run individually. Set up and tear down chains are easy to understand. @Ignore, @NotYetImplemented and @Parameterized are supported for tests. And all the other benefits of JUnit 4 over JUnit 3.8 are available.

UI plug-in tests migrated to Groovy

Closures. List and map literals. Multi-line strings for inline Groovy/Java sources. And all the other benefits of Groovy.

Icons for files, views, wizards, features, and the editor tab

Icon comparisons

JDT overlay icons are used on source file icons to provide a familiar look and feel. Overlays are applied to the lower-left corner to leave room for other decorations like class type (upper-right corner -- abstract, interface, etc.) and source control status (lower-right corner).

Preferences layout and persistence

Many of the Groovy preference nodes have been moved under Editor. Individual content assist preferences have been moved from Groovy to Content Assist and have been reworded for improved clarity of purpose.

Workspace preferences changes

Persistence of the global Groovy Classpath Container preference has been fixed. Restore Defaults on the project's Groovy Compiler page works properly for any permutation of preference values. JUnit monospace font preference has been restored to working condition.

Organize Imports clean-up action

Organize Imports (Ctrl+Shift+O) has been stabilized and now works for types appearing in many more places in a source file, incl. casts, coercions, generics, annotations, throws clauses, catch parameters, for-each parameters, etc. Also, support for static imports has been added. Organize Imports can viably be enabled as a Save Action for a project now. It will not run if the source unit has a syntax error.

Previews for all quick assists

Groovy Editor quick assists (Ctrl+1) show a preview of the proposed change to prevent you from being surprised. The preview pane is the same as the Java Editor provides for many of its quick assists. Insertions are indicated with boldface.

Quick Assist Preview for Extract to local variable

Add Import for selection editor action

Add Import (Ctrl+Shift+M) has been fully realized. This action converts a fully-qualified expression like java.util.regex.Pattern.compile('123') to import static java.util.regex.Pattern.compile and compile('123'). And it can be used to look up unresolved types and present a choice dialog in the case of multiple matches. Add Import now respects your import order and semicolon preferences as well.

Convert accessor to property editor action and quick assist

Replace method call with property expression (Ctrl+Shift+,) has been added to the Groovy Editor > Source context menu as well as the quick assist menu. This action converts foo.getBar() to foo.bar and foo.setBar(X) to foo.bar = X.

Convert def to inferred type quick assist

Replace dynamic type (aka def keyword) with inferred type has been added to the quick assist menu. This new action leverages the power of the type inferencing engine. The declared type may be many steps removed from your local variable, so it may be quicker to type def and then use the quick assist.

Quick Assist for Replace with inferred type

Convert local variable to field support for scripts

Quick assist for converting local variable declarations to field declarations has been enhanced to convert locals to fields in scripts using the @Field transform.

Convert to multi-line string support for concatenation sequences

Quick assist for converting single-line string literals has been enhanced to convert a string concatenation sequence to a multi-line string as well. Simply select the sequence (or place the caret adjacent to the last + operator) and choose "Convert to multi-line string" from the Quick Assist (Ctrl+1) menu. If the selected expression includes any non-string expressions, they will be inlined into a multi-line GString expression and embedded newline characters will cause the multi-line string to start a new line.

So, for example:

    'one\n' +
    'two\n' +
    System.currentTimeMillis()

becomes:

   """one
   two
   ${System.currentTimeMillis()}"""

Support for Compiler Configuration

Support for per-project compiler config scripts has been added to the Eclipse UI, Eclipse CLI and Maven compilers. This replaces the unpublished and experimental property-based greclipse.extraImports and greclipse.customizerClassesList features.

Groovy compiler project preferences

Groovy compiler configuration script

This example leverages the automatic import of CompilerCustomizationBuilder's static member withConfig -- available since Groovy 2.1. More examples of compiler configuration are discussed in the Groovy 1.8 and Groovy 2.1 release notes.

Note: Before editing your config script, you may want to disable it for the project or use the plain-text editor. The Groovy Editor will apply the script even when editing the script itself.

Support for Type Filters, Content Assist Favorites, and Build Access Rules

Support for JDT's classpath features has been improved. Java Type Filters (Window > Preferences > Java > Appearance > Type Filters) are fully supported in the Groovy Editor when performing content assist or organizing imports. Favorites (Window > Preferences > Java > Editor > Content Assist > Favorites) are also supported for content assist of variable expressions. Lastly, Build Access Rules inclusions and exclusions are supported when resolving types.

Improvements to groovy.lang.DelegatesTo annotation support

Previous releases supported the basic @DelegatesTo(Type) form for improved editor support of methods that accept a Closure. The @DelegatesTo attributes value=DelegatesTo.Target, target='name', strategy=n and genericTypeIndex=n are all supported. type='pack.Type' support is stubbed out, but not finished. Note: @ClosureParams remains unsupported.

Improvements to source folding

Rules for source folding have been fixed or enhanced to support folding of static initializers, multi-line closures, and multi-line comments within scripts.

Folding of closures and initializers

Folding of script comments and members

Improvements to script outline

Grapes can be seen in the Outline view. Toolbar filters have been enabled to match the Java view. Script members are more accurately represented.

Outline view of script grapes and members

Improvements to type inferencing and semantic highlighting

The type inferencing/code visitation engine has received a number of upgrades. Code hover/select works for most occurrences of a type, field, method or property in a source file. Code hover on packages in fully-qualified names has been added. Code hover/select on keywords and operators has been suppressed. Support for @TypeChecked and @CompileStatic transformations has been improved. In general, code hover/select should now work in the Groovy Editor much the same as it does in the Java Editor.

The improvements to inferencing/visitation have a trickle down effect on many related features, including Semantic Highlighting, Content Assist, Quick Assist, Refactoring and more. Specifically for highlighting, support for a number of syntax elements has been added, fixed or improved:

  • traits
  • number literals
  • map constructors
  • anon. inner classes
  • closures in closures
  • annotation attributes
  • fields versus accessors
  • parameters and variables
  • category (aka Groovy) methods
  • methods accessed as properties
  • overloaded and @Memoized methods
  • @Lazy and script @Field fields, incl. initializers
  • @CompileStatic and @TypeChecked classes and methods

Semantic highlighting 2.9.2 versus 2.9.1

This sample compares 2.9.2 (on the left) to 2.9.1 (on the right). There are differences on most lines. Notice especially in the Date map constructor that 2.9.2 shows the year and month properties as deprecated and the day property as unknown. And in the same block, use and daylightSavingsOffset are indicated as category methods, not just plain methods.

This next sample shows special highlighting of a regular expression with inline comments -- available for slashy and dollar-slashy strings.

Semantic highlighting of regular expressions

Improvements to DSLDs for built-in AST transforms

DSLD suggestions for Category AST transform

DSLD suggestions for Newify AST transform

DSLD suggestions for Newify AST transform

DSLD suggestions for SelfType AST transform

DSLD suggestions for Sortable AST transform

DSLD suggestions for Singleton AST transform

Concurrent modification exceptions in the DSLD subsystem have been corrected with proper synchronization of data structures.

Annotations included in JDT model

Prior versions of Greclipse had a few special-case checks to support @Test and @RunWith for JUnit/Spock. But most annotations on Groovy types, fields, and methods were not visible to the JDT tooling. In this release, all annotations are represented fully in the JDT model. This allows full support for errors/warnings against annotations, as well as suppressions using @SuppressWarnings. And things like null safety checks (@NonNull, @Nullable, etc.) work properly.

Content assist for annotations

Annotation types can be completed starting from just an @. Attribute names and values can be completed within an annotation's parentheses. And annotation collector annotations are recognized as annotations for content assist and type inferencing -- once compiled they are actually plain classes in the type system.

Content assist for annotations

Previously, CompileDynamic would not be listed in content assist for an annotation context and it would have shown with a C icon in content assist for a type.

Content assist for assignment statements

Content assist for local variable assignment statements has been improved to allow completion proposals for Type name = |. Previously this would have caused an unrecoverable parser error, preventing content assist proposals.

Content assist for method pointer and field access operators

Content assist for method pointers (.& operator) has been added and direct field access (.@ operator) has been improved.

Content assist for method pointers

Content assist templates

Built-in templates for use blocks, JUnit 4, and GContracts have been added. Duplicate ID issues have been fixed.

Traits

Groovy Eclipse now supports Traits with the Groovy 2.3 compiler. A trait is like an interface and can be implemented by your classes. However, Traits can also have fields and methods. Multiple Traits can be composed onto a class without using multiple inheritance and avoiding the "diamond problem".

More details about traits can be found in the Groovy 2.3 docs.

Support for @AnnotationCollector

Greclipse now supports the use of 'AnnotationCollector' GRECLIPSE-1719 The AnnotationCollector tranfsform allows creating annotations that serve as aliases for a group of one or more other annotations.

Content Assist

Content assist is more accurate, it now considers method argument types rather than just the number of arguments GRECLIPSE-1573.
