this fixes an issue (ccw 531) when importing this project in eclipse+CCW

https://code.google.com/p/counterclockwise/issues/detail?id=531
the example solution was suggested by Laurent as seen in comments
(thanks!)

Basically, I couldn't use this project in eclipse+ccw because the folders would be detected wrongly, so I would get this:

instead of this:

(would've used github for images but it says " Something went really wrong and we can't process that image. ")
