I'm using eclipse_3.7.2 with m2eclipse_1.0.200 and I'm getting a NullPointerException when running Project > Clean then Build on a set of projects I checked out as Maven projects:
Errors running builder 'Maven Project Builder' on project '[my project]'. java.lang.NullPointerException at org.eclipse.m2core.internal.lifecyclemapping.model.PluginExecutionFilter.match(PluginExecutionFilter.java:304) at org.eclipse.m2core.internal.lifecyclemapping.

It doesn't seem to affect the maven build but it is annoying and prevents checking out projects into a Working Set. Unfortunately I need to stick with the versions I have and cannot run milestones. Anyone have any ideas? Thanks, Craig
