If you want add a "Scala sub-project" into your Java project, you can use the "New Module" functionality.

To do this...

  1. Bring up the right mouse button pop-up menu on your Java project root
  2. Select "New/Module..."
  3. From the "New Module" dialog that appears, select "Scala" from the left side (assuming you have already added the Scala plug-in)

This will do all the setup work needed for you to have a Scala project.

Protip: You will want to change the line within the automatically generated build.sbt (lazy val root = (project in file(".")) to something like...

lazy val root = (project in file("scalasubprojectfoldername")

This will ensure the project and target folders will remain in the Scala sub-project, as opposed to being placed into the root Java project.

To add Scala support to existing module:

  1. Right-click the module in Project View, choose “Add Framework Support…”
  2. Check “Scala” in technologies list (unavailable if module has Scala facet attached)
  3. Provide a path to Scala installation (if not detected)
