.classpath and .project files are *meant to be versioned*

As is clearly stated in the [eclipse documentation](http://wiki.eclipse.org/FAQ_How_do_I_set_up_a_Java_project_to_share_in_a_repository%3F).

be sure/do not have any references on those

Also .launch configurations are generally meant to be versioned when
saved under project location. See for instance :
