      public class Groovyc
      extends org.apache.tools.ant.taskdefs.MatchingTask

  Compiles Groovy source files using Ant.

  Typically involves using Ant from the command-line and an Ant build file such as:

       <?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="${groovy.home}/lib">
             <include name="groovy-*${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>

  This task can take the following arguments:

  - srcdir
  - scriptExtension
  - targetBytecode
  - destdir
  - sourcepath
  - sourcepathRef
  - classpath
  - classpathRef
  - listfiles
  - failonerror
  - proceed
  - memoryInitialSize
  - memoryMaximumSize
  - encoding
  - verbose
  - includeantruntime
  - includejavaruntime
  - fork
  - javaHome
  - executable
  - updatedProperty
  - errorProperty
  - includeDestClasses
  - jointCompilationOptions
  - stacktrace
  - indy
  - scriptBaseClass
  - stubdir
  - keepStubs
  - forceLookupUnnamedFiles
  - configscript
  - parameters
  And these nested tasks:
  - javac
  Of these arguments, the srcdir and destdir are required.

  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.

  A more elaborate build file showing joint compilation:

       <?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="${groovy.home}/lib">
             <include name="groovy-*${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>

  Based on the implementation of the Javac task in Apache Ant.

  Can also be used from `AntBuilder` to allow the build file to be scripted in Groovy.

    - #### setForceLookupUnnamedFiles

          public void setForceLookupUnnamedFiles(boolean forceLookupUnnamedFiles)

      Set the forceLookupUnnamedFiles flag. Defaults to false.

      The Groovyc Ant task is frequently used in the context of a build system that knows the complete list of source files to be compiled. In such a context, it is wasteful for the Groovy compiler to go searching the classpath when looking for source files and hence by default the Groovyc Ant task calls the compiler in a special mode with such searching turned off. If you wish the compiler to search for source files then you need to set this flag to `true`.

      Parameters:
        `forceLookupUnnamedFiles` - should unnamed source files be searched for on the classpath

    - #### getForceLookupUnnamedFiles

          public boolean getForceLookupUnnamedFiles()

      Gets the forceLookupUnnamedFiles flag.
      Returns:
        the forceLookupUnnamedFiles flag

    - #### setParameters

          public void setParameters(boolean parameters)

      Parameters:
        `parameters` - set to true to generate metadata.

    - #### getParameters

          public boolean getParameters()

      Returns true if parameter metadata generation has been enabled.
