## org.codehaus.groovy.ant
Class Groovyc

    java.lang.Object
      org.apache.tools.ant.ProjectComponent
          org.apache.tools.ant.Task
              org.apache.tools.ant.taskdefs.MatchingTask
                  org.codehaus.groovy.ant.Groovyc

All Implemented Interfaces:
  Cloneable, SelectorContainer

    public class Groovyc

extends MatchingTask

Compiles Groovy source files. This task can take the following arguments:

- srcdir
- destdir
- classpath
- encoding
- verbose
- failonerror
- includeantruntime
- includejavaruntime
- memoryInitialSize
- memoryMaximumSize
- fork
- stacktrace

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.

Based heavily on the Javac implementation in Ant.
