Passing a FileSet/DirSet directly to the AntBuilder

[John W. Lewis]

I have an AntBuilder question:

Given a set:

        def set = ant.fileset(dir:'mydir', id:'myfileset')

This works:

        ant.'mytask'(attr:'attr') {
                fileset(refid:'myfileset')
        }

But, I can't get this to work:

        ant.'mytask'(attr:'attr') {
                set
        }

Is there a way?   I'm wanting to do this:

        myclosure = { set ->
                ant.'mytask'(attr:'attr') {
                        set
                }
        }

        myclosure(ant.fileset(dir:'mydir'))


Thanks for any help,

John

In the Grails scripts we set up closures for the filesets:

  def filesets = {
      fileset(dir: "mydir")
  }

  myclosure = { set ->
      ant.'mytask'(attr:'attr', set)
  }

  myclosure(filesets)

I don't think there's any other way. AntBuilder is useful for some
things, but Ant itself is not designed for this kind of work so
externally driving it can be tricky at best. It doesn't have a proper
public API for doing things like passing in filesets and other such
stuff. Happy to be proved wrong though :)

Cheers,

Peter

That works.   Thanks.  I ended up doing this (thanks to Jurgen Hermann on the groovy mailing list):

         myclosure = { set ->
                 ant.'mytask'(attr:'attr', set)
         }
 
         myclosure { ant.fileset(dir:'mydir') }

That is pretty much what you suggested.

Thanks again!

John
