There seem to be a number of issues here are several:
a.) different poms with dependencies on the same jar but using different
groupId/artifactId (ex. jetty/jetty and jetty/org.mortbay.jetty) causing
multiple copies to be downloaded and stored
b.) poms using syntax like ${commons_beanutils_version} which isn't valid
(as far as I know)
I wish there was something I could do to help fix these problem maybe if
there were a way to know the maintainer of parts of the repository so they
could be contacted and told of specific issues?
