groovy support outside of 'source' folders

Hi,

I am using groovy based build systems like 'gradle' and 'gant'. These files like 'build.gant' are normally placed in the project or module root, which is therefore not marked as a source folder. As from 'Diana', these groovy files are not treated as groovy files anymore unless they are actually in a 'source' folder.

Is there any way to mark these files, which are not in 'source' folders, to also be handled as 'groovy' files?

Regards Jaco
