Please report this to the plugin authors, they will contact back the Maven core team if their investigation discovers it's really a core issue and not a plugin bug.
> Strange exception when running Maven from Hudson
> ------------------------------------------------

> Key: MNG-4659
> URL: http://jira.codehaus.org/browse/MNG-4659
> Project: Maven 2 & 3
> Issue Type: Bug
> Affects Versions: 2.2.1
> Environment: uname -a output:
> Linux changedTHIS.com 2.6.9-89.0.9.ELsmp #1 SMP Wed Aug 19 08:06:10 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

> Running Hudson with a LOT of jobs defined. We recently moved all of our group's jobs up to Maven 2.2.1; however, several other groups still run their jobs with Maven 2.0.9. Since we made this change, it seems that about once a day we get the exception/stack trace shown below. Note: all of the jobs in our Hudson environment run as the same user. To make the error go away, one needs to go the hudson user's .m2/repository directory and type: rm -rf com
> then when you re-run the job it works successfully! So even though the error seems like a Clover one, because of the fix, I thought it should be reported here. Sorry if this was a mistake!
