I believe the scala plugin is not installed on your machine.
So, please try to install it either via the Synaptic-Package-Manger or with command apt-get install, and try to compile the project.

and

*with -X option ===>* Almost same error message as above.

I am using *Ubuntu 12.04.1 LTS* & *kernal 3.2.0-36-virtual*.


Please help me out to resolve this installation problem.

Thanks for your precious advices.
