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?
