As some of you undoubtably have noticed there have been quite a few regressions on groovy. This is due to
pr.willowgarage.com going offline. We have mirrored the content onto
downloads.ros.org. I am working on getting a redirect setup which I believe should fix all the failures. The other solution is to change all the references from
pr.willowgarage.com to
downloads.ros.org for things like test data. However, at the moment I believe I can get the redirect setup so rereleasing should not be necessary.
