Note for others : this is a command you have to type: you may need bzr installed also, it's a program similar to cvs or svn.
Right now I have 22 errors and 2 warnings. Obviously I am missing some libraries (Where is Scanner located?).
EDIT: I needed to do a couple of things: 1) make sure I had Sun's Java installed, not just OpenJDK 2) Make sure the Workspace properties are set to compiler compliance level of 6.0. And so far, it works! Now I have to get cracking I suppose.
