title: Changing Scala sources directory in SBT
body: <p>I'm having quite a few troubles pointing at a custom directory for Scala source-files in SBT. </p>
  
  <p>I would like sbt to compile scala-files from a given directory instead of the regular <code>src/main/scala</code> directory.</p>
  
  <p>I have tried both defining a .sbt and .scala project files, setting <code>baseDirectory</code>, <code>scalaSource</code> (and <code>scalaSource</code> <strong>s</strong> in the .scala file). I've also toyed around with everything from system-absolute to relative paths but nothing seems to work. It cannot locate any .scala file under the specified directory.</p>
  
  <p>What are the proper ways to handle this?</p>
