Compiling the Mendix Runtime

Hey everyone, I'm new to the mendix community. I saw the press release on twitter from Johan den Haan, and have been trying to compile the mendix runtime because I'd like to play around with it. So far, no luck though... When I open the project in eclipse I get a zillion compile errors, such as "AbstractMojo cannot be resolved to a type". It seems as if the runtime depends on a lot of libraries, but I can't figure out which exactly. Documentation seems to be lacking as well, unfortunately :( Has anyone had more luck? Here's the link to the source, by the way:
