Comment 1 andy CLA 2010-12-23 08:33:58 EST
I also tested with only installing m2eclipse. - and theres the error, too!

Steps to Reproduce:
1. Download and start eclipse classic 3.5.2
2. install maven integration (0.12.0.20101115-1102.jar)for eclipse from updfate site http://m2eclipse.sonatype.org/sites/m2e
3. restart eclipse and look into error log

Here the log file from now:

Comment 4 Pascal Rapicault CLA 2011-03-03 20:45:01 EST
This has been fixed in 0.13 that is work in progress until mid June when Indigo
ship.
In the meantime you can try it from
http://download.eclipse.org/technology/updates/M or
http://download.eclipse.org/technology/updates/N if you want to be on the
bleeding edge.
