It seems that there are some issues with accessing the Scala standard libraries from a jps-plugin. For instance, when attempting to do something like `myString.nonEmpty`, I get -
Error: java.lang.NoClassDefFoundError: scala/collection/immutable/StringOps
The main plugin module works fine with the scala-sdk-2.11.7 global library, so I assumed it should work with the jps-plugin as well.
Note that things seem to work once the plugin is deployed; however, I cannot seem to get it to work when running/debugging the plugin.
Here's the exact code that causes the issue - https://github.com/carymrobbins/intellij-haskforce/blob/ae9fa3ad7c02aa1a04d640d8624bc7f3d972569e/jps-plugin/src/com/haskforce/jps/stack/StackBuilder.scala#L35-L36
Most of the .idea files are included in that repo, as well as all of the *.iml files.
