[m2e-users] NPE on import existing maven projects

[Craig Foote <craigfoote@xxxxxxxxx>]

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

It identifies a single project which, like several other seemingly fine projects, uses the org-apache-felix:maven-bundle-plugin_2.1.0 to generate its MANIFEST.MF.

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
