How to use my classes from Scala worksheet in IntelliJ CE with Scala plugin?

Question

I cannot use my classes from the Scala worksheet in IntelliJ CE with the Scala plugin.

I do the following:

• Create a Scala SBT project.

• In src / main / scala, create the test1 package.

• In this package, create a class

 package test1 class TestClass { } 

4. In the same package, create Scala worksheet ws1.sc, create a ws1 object inside it, add a couple of expressions inside it. It is working.

5. When I add new ScalaTest to the new ScalaTest object, IntelliJ adds import test1.ScalaTest , but the worksheet evaluation does not work.

If I add package test1 to my sheet, it doesn’t work at all, with the warning “The package name does not match the directory structure, this may cause a problem with resolving classes from the file”

Any ideas how to use my classes from a worksheet?

You can use eclipse compatibility :

Settings → Languages ​​and framework → Scala → Worksheet → use eclipse compatibility mode

You should mark "Make a project" next to "Interactive mode"
