> Groovyc ant task can overflow Windows command line if classpath is large
> ------------------------------------------------------------------------

> The groovyc ant adapter tries to account for the 32K command line length
> limit on windows in its addSourceFiles method. However, if the command line
> gets long for other reasons -- we include a number of libraries in our
> compiled projects -- the command line can still be overflown.
> This results in:
> {code}
> CompileAntScript.xml:129: Error running forked groovyc.

> Would it be possible to add command line length checking to {{runForked}}
> instead of {{addSourceFiles}} and use a command file for groovyc to prevent
> command line overflow? Without this, we are having to use a lot of verbose
> workarounds in Ant.
