We are getting this error in the Eclipse Maven plugin (using 2.1.1). We were using 2.1.1 and getting the same error using the IDEA compiler, but on swapping to 2.1.2 this problem has gone away and all our tests using Mockito now work with @CompileStatic tagged. When attempting to build under Eclipse Maven with the additional 2.1.1 dependency, this problem still occurs.

Any chance of a 2.1.2?
