Description

Two files in the 'pkg' package:

MyClass.groovy

package pkg 
class HasClass { static class MyClass {} }

 

HasClass.groovy

package pkg
private static void foo(HasClass.MyClass... val) {}
//pkg.HasClass.MyClass[] val // Also Fails
//pkg.HasClass.MyClass val // Does not fail

Results in the following error:
 

/home/ianl/IdeaProjects/VariousGroovy/src/main/groovy/pkg/UsesClass.groovy: 3: unable to resolve class HasClass.MyClass[] 
 @ line 3, column 25.
   private static void foo(HasClass.MyClass... val) {}
                           ^

This fails only for arrays, not single references. It does not occur if the files are in the default package.

It is also possible to work around it with a static import:
 

HasClass.groovy

package pkg
import static HasClass.MyClass // Now it doesn't fail
private static void foo(MyClass... val) {}
