Error: scala: No 'scala-library*.jar' in Scala compiler library

Question

Environment: Play 2.3.0/Scala 2.11.1/IntelliJ 13.1

I used Typesafe Activator 1.2.1 to create a new project with Scala 2.11.1. After the project was created, I ran gen-idea. The generated IDEA project fails to compile with the error:

Error: scala: No 'scala-library*.jar' in Scala compiler library in test

Am I doing something wrong? Workaround?

Answer 1

1. Open File -> Project Structures -> Libraries, remove any scala sdk in it, e.g. scala-sdk-2.11.8 in the following image.

2. Click on +, then Scala SDK.

3. Select the right Scala SDK from the list, for me, it's Ivy-Scala-2.11.8 shown in the picture.

4. Select the current project(mine is spark-test), click OK.

5. Then click OK to close it.

6. Run again, it should work now.

Answer 2

Since IDEA 13 you should use SBT support which is bundled with Scala plugin.

With it there is no need to add third-party SBT plugins and run special commands; just import the project using "File -> Import project..." menu item, and it will automatically load SBT project structure and its dependencies.
