I'm using IntelliJ 12.1 on Mac. I'll update to 12.1.1 to test. Yup that is working… I tried uninstalling the plugin and then installing the exact version that's checked in. It's still working for me… hmm..
I have some logging in the code that processes the source jars, however there is no plugin code for getting the menu item to show, it's done through configuration.
You could try checking out the project and then creating a intellij plugin run profile… This will ask you to create an SDK, you'll point to the intellij program folder (should be there by default) then it will ask which version of java you want to use.
The run profile should spin up a new instance of intellij with the plugin enabled. There may be some debugging you can do from that point. I didn't really have to.
One issue I did run into when I was developing this was that I was compiling the plugin with java 7 however intellij runs with java 6. In that case the menu item did not show up when I used the jar to install the plugin (it did work via the run profile which also ran intellij with java 7.) It's possible that I need to commit a new version of the jar compiled with java 6… although I thought I had done that already. Hmm… I just checked and the version that's checked in was compiled for java 6…
Are you using the jar from bitbucket or are you re-compiling it?
