title: Scala project does not automatically build in Eclipse
body: <p>I copied the examples folder from scala-2.7.7.final-devel-docs to the src folder of a scala project. </p>
  
  <p>But the source files will not compiled unless I change them manually. "Project/Build automatically" is checked. </p>
  
  <p>I'm using the Scala Eclipse Plugin 2.7.7-final</p>
  
  <p>How can I achieve that this works like in java projects?</p>
