Ok, so I _had_ it working, I thought, under 8.0 M1 (not positive of version, but know I had something properly _executing_ my groovy scripts, though not highlighting properly).
I've installed groovy-1.5.7 on my system.
I've created a new project, added groovy facet and added global lib of Groovy using the embeddable groovy-all JAR file.
No highlighting, no recognizing of runnable scripts, nothing, even when adding files through menu such as "New->Groovy Script".
I've googled and searched these forums, release notes, etc and I'm not new to IDEA (using since 5.0).
What am I missing?
Attached are screens of my settings, except plugins as I only had ONE non-default plugin (older one for highlighting Groovy syntax, but which I disabled and nothing changes.
