Getting OverlappingFileLockException.

[bardam]

I get the following exception when running the plugin in my CI server,
I have zinc installed on the machine.
It seems that the plugin checks the scala version which leads to this exception.
The maven build runs in several threads.

I'm not a Zinc user, but Zinc seems to lock files, so it can't run in concurrent Thread.

Zinc server support has been dropped, see #299.
Closing.
