Jump to definition in source of gradle tasks

Hi,

I have recently started to load some of of gradle projects into as IntelliJ as gradle projects rather than Java projects.  This has been a pretty good experience so far, and all of the sub projects were discovered correctly and all the gradle tasks for every project were found.

I can run tasks using the gradle pane/window, but the jump to source option for any gradle task is greyed out.  So I have to locate the build script containing the task my self.

I have also tried this with the samples provided in the latest gradle distribution and this menu option (jump to source) is always greyed out.

Why is this?  It would be great to be able to jump straight to the task definition in the actual source file.

Thanks

Martin
