MultipleCompilationException - Groovy SourceSet can't see Java SourceSet

[marek-parfianowicz]

Using the gradle clover plugin causes an exception (see readme.txt) because the groovy source set can’t see the java source set.

I ran into the same issue. I also created a minimal grails project which reproduces it (before finding this issue report):

I tried to work around this issue using the additionalSourceSet option, but I could not get it to work.
