Output path is shared between the same module error

Question

When I try to compile any class in my project I get the error below:

Error scala: Output path .../eval/target/test-classes is shared between: Module \'eval\' tes         


        

Answer 1

I had 2 differently named versions of the same module and needed to delete one to avoid this clash. This is what worked for me:

In IntelliJ IDEA go to File -> Project Structure -> Modules -> Your Project -> Paths

Ensure each Modules "Output path" and "Test output path" locations are unique across all your modules. If you have more than one module with the same paths, you can specify unique paths for every module or as in my case, delete the module that you do not require as it was a duplicate of an existing module
