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
- stubdir

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.
