Re: NullPointerException in ProcessArchivaArtifactClosure while scanning repository

Posted by Brett Porter <br...@gmail.com>.
The issue has been fixed in 1.0.2-SNAPSHOT. There are a few different
causes, usually revealed by the stack trace that follows. It's often
an unrecognised path format being scanned.

Cheers,
Brett
