Corrupt local maven metadata

[Holly Cummins <ho...@googlemail.com>]

Hello,

I've just mailed you about the ubuntu build engines being jammed.
That's now fixed, which is great, but now I have another build problem
which I don't think I can resolve. Our builds on ubuntu2 are failing
with the following (see for example
https://builds.apache.org/job/Aries/1635):

Caused by: org.apache.maven.artifact.resolver.ArtifactResolutionException:

It looks to me like the maven metadata in the local repository is
corrupt, and could do with deleting. I considered running a
dependency:purge-local-repository job, but the web suggests that can
sometimes corrupt things on its own, and I'm not sure it would even
work if the metadata is corrupt. Is it possible to clean the
org/apache/aries sections of the local maven repositories to get our
builds going again, or is there some other way of fixing the problem?

Thanks again,
Holly
