Just this morning our builds on Continuum were failing. Looking at the
logs this is what I see:

I thought this was related to corrupted meta data in the repo folder
so I deleted ~/.m2/repository/org/apache/maven which forced maven to
retrieve all the artifacts and plugins it needs but I am still getting
the same error.
Any idea whats going one ?
