Thanks, this really helped.
Perhaps this should be part of a "Developer / Build Howto" ?


I downloaded the current trunk of pig (via github) and ran into a
completely different hurdle:
With hadoopversion=23 this target is fired
    <target name="include-meta" if="isHadoop23">

And even though I installed ant 1.9.0 (the latest) it causes an NPE in ant
itself.

*BUILD FAILED

*/home/nbasjes/workspace/pig/build.xml:658: The following error occurred

Has anyone seen this too? Is this a bug in ant or am I doing something
wrong?
