title: Output path is shared between the same module error
body: <p>When I try to compile any class in my project I get the error below:</p>
  
  <pre><code>Error scala: Output path .../eval/target/test-classes is shared between: Module 'eval' tests, Module 'eval' tests
        Output path .../eval/target/classes is shared between: Module 'eval' production, Module 'eval' production
        Please configure separate output paths to proceed with the compilation.
  </code></pre>
  
  <p>I've seen how to set the output path in IDEA and I've done it. But as the error claims that it is shared between the same module I couldn't solve it.</p>
  
  <p>Obs.: Using Maven and IntelliJ IDEA.</p>
  
  <p>Please, can anyone help?</p>
