After upgrading to IntelliJ12 I've started experiencing errors while building:
Compiler internal error. Process terminated with exit code 1
with no other details. The IntelliJIdea12 log shows the following:
2013-01-07 12:07:37,317  INFO - ij.compiler.impl.CompileDriver - COMPILATION STARTED
2013-01-07 12:08:55,291  INFO - lij.compiler.impl.CompilerUtil - COMPILATION FINISHED; Errors: 1; warnings: 0 took 77977 ms: 1 min 17sec
FWIW from a terminal window sbt compiles with no problems. I'm running Idea 12.0.1 on OS X Lion and version 0.7.62 of the Scala plugin; the Scala Compiler preferences have "Run internal server" selected.
Is this a bug, a misconfiguration, or something else?
