Repository purge can't deal with arbitrary files in local repo

I clicked the 'Purge' icon next to the DEFAULT repository purge configuration on http://localhost:9080/continuum/admin/purgeConfigList.action, and got a bunch of these errors (below) in continuum.log.

In general it is not an error to have an arbitrary file deployed alongside the artifact. This one in particular (resolver-status.properties) seems to be generated by Maven (see MNG-3421).

Until the purge logic can handle it, this should probably be a warning that the file was encountered and ignored, instead of an error and stacktrace.
