I have been using maven pretty successfully for low-end java
programming--I'm not much of a developer. I have finally convinced a few
folks to potentially work with me on some projects at work and thought
setting up a repository manager would be a good idea. The nexus setup
pretty simple and I changed my settings.xml to include a mirror to the local
nexus installation (version 1.3.6, open source). I can see artifacts moving
into the cache just fine as they are used in builds.
I have a project that I have been building fine until the above process was
completed. Now, during site building under m2eclipse, I get the error
below. Any suggestions on what needs to change? It appears that
commons-lang is not being picked up as a dependency?
Thanks,
Sean
