title: Building a scala app with maven (that has java source mixed in)
body: <p>I have an application where I would like to have mixed Java and Scala source (actually its migrating a java app to scala - but a bit at a time). </p>
  
  <p>I can make this work in IDEs just fine, very nice. But I am not sure how to do this with maven - scalac can compile java and scala intertwined, but how to I set up maven for the module? </p>
  
  <p>Also, does my scala source have to be a different folder to the java? </p>
