/**
* Compiles Groovy source files using Ant.
* <p>
* Typically involves using Ant from the command-line and an Ant build file such as:
* <pre>
* <?xml version="1.0"?>
* <project name="MyGroovyBuild" default="compile">
* <property name="groovy.home" value="/Path/To/Groovy"/>
* <property name="groovy.version" value="X.Y.Z"/>
* <path id="groovy.classpath">
* <fileset dir="${groovy.home}/embeddable">
* <include name="groovy-all-${groovy.version}.jar" />
* </fileset>
* </path>
* <taskdef name="groovyc" classname="org.codehaus.groovy.ant.Groovyc" classpathref="groovy.classpath"/>
*
* <target name="compile" description="compile groovy sources">
* <groovyc srcdir="src" listfiles="true" classpathref="groovy.classpath"/>
* </target>
* </project>
* </pre>
* <p>
* This task can take the following arguments:
* <ul>
* <li>srcdir</li>
* <li>scriptExtension</li>
* <li>targetBytecode</li>
* <li>destdir</li>
* <li>sourcepath</li>
* <li>sourcepathRef</li>
* <li>classpath</li>
* <li>classpathRef</li>
* <li>listfiles</li>
* <li>failonerror</li>
* <li>proceed</li>
* <li>memoryInitialSize</li>
* <li>memoryMaximumSize</li>
* <li>encoding</li>
* <li>verbose</li>
* <li>includeantruntime</li>
* <li>includejavaruntime</li>
* <li>fork</li>
* <li>javaHome</li>
* <li>executable</li>
* <li>updatedProperty</li>
* <li>errorProperty</li>
* <li>includeDestClasses</li>
* <li>jointCompilationOptions</li>
* <li>stacktrace</li>
* <li>indy</li>
* <li>scriptBaseClass</li>
* <li>stubdir</li>
* <li>keepStubs</li>
* <li>forceLookupUnnamedFiles</li>
* <li>configscript</li>
* <li>parameters</li>
* </ul>
* And these nested tasks:
* <ul>
* <li>javac</li>
* </ul>
* Of these arguments, the <b>srcdir</b> and <b>destdir</b> are required.
* <p>
* <p>When this task executes, it will recursively scan srcdir and destdir looking for Groovy source files
* to compile. This task makes its compile decision based on timestamp.
* <p>
* A more elaborate build file showing joint compilation:
* <pre>
* <?xml version="1.0"?>
* <project name="MyJointBuild" default="compile">
* <property name="groovy.home" value="/Path/To/Groovy"/>
* <property name="groovy.version" value="X.Y.Z"/>
*
* <path id="groovy.classpath">
* <fileset dir="${groovy.home}/embeddable">
* <include name="groovy-all-${groovy.version}.jar" />
* </fileset>
* </path>
*
* <target name="clean" description="remove all built files">
* <delete dir="classes" />
* </target>
*
* <target name="compile" depends="init" description="compile java and groovy sources">
* <mkdir dir="classes" />
* <groovyc destdir="classes" srcdir="src" listfiles="true" keepStubs="true" stubdir="stubs">
* <javac debug="on" deprecation="true"/>
* <classpath>
* <fileset dir="classes"/>
* <path refid="groovy.classpath"/>
* </classpath>
* </groovyc>
* </target>
*
* <target name="init">
* <taskdef name="groovyc" classname="org.codehaus.groovy.ant.Groovyc" classpathref="groovy.classpath"/>
* </target>
* </project>
* </pre>
* <p>
* Based heavily on the implementation of the Javac task in Apache Ant.
* <p>
* Can also be used from {@link groovy.util.AntBuilder} to allow the build file to be scripted in Groovy.
