When building from source, I used to work with
the eclipse:clean and eclipse:eclipse targets to generate
fresh eclipse project and classpath settings after a pull.
This doesn't work any longer out of the box with the latest source.
I get something like:
<snip>

Can anyone confirm the problem?
I've worked around it by using
mvn eclipse:eclipse -Denforcer.skip=true
to skip the enforcer plugin settings, so it's not that a problem, but
perhaps the maven gurus out there can fix it sometime.
Thanks,
Georg
