I had been using the IDE for several days straight now with a project which builds an EAR from a WAR and a JAR file. After a few days of building the project and working with it, I noticed that it was adding some application descriptors to the project that I told it to no longer generate.
It wouldn't stop generating them. I would tell it to stop exporting certain libraries into the war file, and everytime I would look at the exploded war in the ear - those libraries would still be there.
To top it all off I just told it to make my project after having had it make the project no fewer than 30 times today and I'm greeted with:
Information:Compilation completed with 1 error and 0 warnings
Error:No Java compiler available
No Java compiler available? Did you delete it? I open a shell in OSX and type javac -version and its still there 1_5_06. I look at the IDE to make sure it didn't delete my project settings, nope they are still the same. So I can only assume that IDEA has fubar'd itself into a state where it just doesn't know how to work anymore.
