Jeff Black commented on MWAR-280:
---------------------------------
I tested with 2.4-SNAP, and got comparable build times, but I was unable to
duplicate the original issue with version 2.2. I would be interested to know
if other can still duplicate this issue.
War project with one overlay, goals: clean install:
Maven 3.0.5
- war plugin 2.1.1, build time 54s avg.
- war plugin 2.2, build time 58s avg.
- war plugin 2.4-SNAP, build time 40s avg.
Maven 2.2.1
- war plugin 2.1.1, build time 54s avg.
- war plugin 2.2, build time 54s avg.
- war plugin 2.4-SNAP, build time 52s avg.
> Big performance hit in overlay
