Actually, I spoke too soon. It appears that if executed under non-root the build fails as follows:
[exec] BUILD FAILED
[exec] /usr/local/apache-forrest/main/targets/plugins.xml:374: Directory /usr/local/apache-forrest/build/plugins creation was not successful for an unknown reason
Can you, please, take care of the forrest issue?
As an aside: I though Pig migrated away from forrest. Am I missing something?
