Brian Fox commented on MNG-3438:
--------------------------------
This seems to be caused by the XarMojo trying to use some old plexus dependency
that causes conflicts in the logging impl.
It works in 2.1 because there plugins are completely isolated from the core. If
you can identify which jar is causing the conflict, we might be able to figure
out what can be done to restore compatibility.
