This is using Jetgroovy .1 from the plugin download and Idea 7255. I don't seem to be able to get other builds to work and can't build from source as many libraries are unavailable.
My issue is that after restarting IDEA all my declarations turn red. These are just basic declaring other domain objects from within a domain object. These are of course at the same package level. I also can't use auto complete features. Is it just me having this problem? Has anyone else encountered this? Is there a workaround?
