I was able to replicate the Eclipse issues using a clean clone of the
repository and the short version is that Eclipse basically doesn't know
what to do if there is no project file present. It looks like dropping a
Maven pom.xml in will allow Eclipse to manage things as a Maven project,
but it's going to take me a couple days to do that. Would there be any
interest in incorporating that into the official repository?
