couldn't find anything relevant on Google...

Answer 1

So to resume my comments:

The compiler library you should use is : Maven: org.scala-lang:scala-compiler-bundle:2.9.0-1

I don't know why it haven't been created when you opened the Goose project.

But you can create it yourself:

Open the library settings and spot where your system download the maven libraries by clicking eg on: Maven: org.scala-lang:scala-library:2.9.0-1.

Then click on New Project Library, and add to it both Maven: org.scala-lang:scala-library:2.9.0-1 and Maven: org.scala-lang:scala-compiler:2.9.0-1. The file selector has an option to display hidden directories, which can be useful.

Then go in the Module settings and change the Scala compiler to the library you just created. (It may take a few seconds before appearing in the list of libraries). It should work fine.
