It's interesting, the lifecycle mapping file under
workspace/.metadata/.plugins/org.eclipse.m2e.core/lifecycle-mapping-metadata.xml
is an empty file. This is a fresh install so I don't think I nuked the
file.
I tried adding a stub with:
<pluginManagement>
<plugins>
</plugins>
</pluginManagement>
That didn't seem to help.

Okay thanks.
Let me see if I can find the life cycle mappings. How will I be
able to identify the missing group/artifact/version?

I haven't looked at this code, but in the past this type of error
was caused by a missing group/artifact/version element in the
lifecycle mappings.

Hi,
I'm trying to use m2eclispe with the mahout project. I'm
getting a "Cannot parse lifecycle mapping metadata..."
error. When I try to open project > properties > maven >
"lifecycle mapping" to fix the issue I get a null pointer
exception. Screen shot and stack trace from the eclipse
error log are show below.
Any suggestions?
