I'm not actually sure about this... but it might be the reason the tests are failing. Master doesn't compile ATM because of a type difference between String and List[String] related to this:

    [error] /Users/bburton/Workspace/assets-loader/plugin/app/com/ee/assets/processors/SimpleFileProcessor.scala:189: type mismatch;
    [error]  found   : List[String]
    [error]  required: String
    [error]       writeToFile(destination, contents)
