@gildegoma You say changing just the check or everything? Because if I make `-f gradlew` and `gradlew check`, for example, the tests break. Maybe I'm configuring things in the wrong way, I don't know.

I've changed locally only the file check, and everything runs fine. If *this* is all the change you suggested, I can update the pull request.

@michaelklishin if we don't find any gradle wrapper, we just continue with the current logic of using `gradle` command directly. If someone is using anything very different I don't think it's a problem because he/she can just overwrite the travis defaults in `.travis.yml`. So... don't think that this will break anything :smile:
