• Create a new Maven module (project) named app-001.

mvn archetype:generate -DgroupId=com.example -DartifactId=app-001 -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.5 -DinteractiveMode=false -DjavaCompilerVersion=21

• Remove the following tags in module's pom.xml:

  • <groupId></groupId>
  • <name></name>
  • <url></url>
  • <properties></properties>
  • <dependencyManagement></dependencyManagement>
  • <pluginManagement></pluginManagement>

• Change directory into app-001, and the maven convention project structure as shown below:

.
├── pom.xml
└── src
    ├── main
    │   └── java
    │       └── com
    │           └── example
    │               └── App.java
    └── test
        └── java
            └── com
                └── example
                    └── AppTest.java

• Check the standard directory layout.
