I just created a repo on github, and achieved to push an existing project from eclispe egit.

Then i cloned it on other platforms ( both macosx and win ), and everything seems perfect, i can see a java project, execute tam command and code and eventually see warnings/errors. But as I try to run i recive

Exception in thread "main" java.lang.NoClassDefFoundError: mypackage/MyClass
Caused by: java.lang.ClassNotFoundException: mypackage/MyClass

the elcipse error log says

Error
Fri Apr 26 17:04:32 CEST 2013
The project description file (.project) for 'TheNameOfTheProject' is missing.  This file contains important information about the project.  The project will not function properly until this file is restored.


i belive there must something to do with classpath file or env var, but the file is present as well as .project and .setting either on remote and in local.

Any idea? thank you.

If you create an identical project on the other platforms, is there any difference to the cloned project?

What do you mean with " execute tam command and code and eventually see warnings/errors"?
