Fluent API options

[pewsplosions]

Hi, I have inherited an old project and have been tasked with upgrading everything at once. It is kind of a nightmare and I don't know a whole lot about all this anyway. One of the upgrades is going from Ant to Gradle and from Java 8 to Java 15 and updating Jaxb to 3.0 as well.

Of all the gradle jaxb plugins I found, this one seemed the best so I went with it. Got everything generating pretty well but it is not quite the same as it used to be. So I was hoping maybe I could get some help on this.

The previous ant target to build looked like this:

    <target name="gen-jaxb" depends="init,clean-gen-jaxb" 
        description="Generates Java classes from the XSD definitions">
        <taskdef name="xjc" classname="com.sun.tools.xjc.XJC2Task">
            <classpath>
                <fileset id="xjc" dir="${deps.dir}/jaxb-xjc" includes="**/*.jar" />
            </classpath>
            <classpath path="${project.buildpath}" />
        </taskdef>
        <xjc destdir="${src}">
            <binding file="bindings.xml"/>
            <schema dir="schemas" includes="**/*.xsd" />
            <arg value="-verbose"/>
            <arg value="-npa"/>
            <arg value="-extension"/>
            <arg value="-Xinject-code"/>
            <arg value="-Xfluent-api"/>
            <arg value="-Xcommons-lang"/>
            <arg value="-Xannotate"/>
        </xjc>
    </target>

I have translated that to this:

plugins {
  id "com.github.bjornvester.xjc" version "1.5.0"
}
dependencies {
  xjc "org.glassfish.jaxb:jaxb-runtime:3.0.0"
  xjc "org.glassfish.jaxb:jaxb-xjc:3.0.0"
}
xjc {
  xjcVersion.set("3.0.0")
  xsdDir.set(file("schemas"))
  outputJavaDir.set(file("src/main/xjc"))
  options.add("-verbose")
  options.add("-npa")
  options.add("-extension")
  options.add("-Xinject-code")
  options.add("-Xfluent-api")
  options.add("-Xcommons-lang")
  options.add("-Xannotate")
}

The first error I've run into for the actual build is the lack of a fluent API. So I'm guessing that I am doing the args wrong in this gradle plugin. I read that options was for 3rd party plugins. So I wasn't sure this would just work anyway. But gave it a shot.

So I guess my question is. How would I translate the args from the ant target to this gradle plugin?

Is it even possible? Or are those only Jaxb 2 options? Or do I need an additional gradle plugin?

I've been working on this about 15 hours straight now so thought I'd stop trying things and ask. :D

Any help is greatly appreciated! :) Thank you.
