Issue#34

@MartinSenne 

I could need some help to let travis executes the tests in project benchmark.
Testing manually works, i.e.

>projects
>project benchmark
> compile
> test

Does exactly what it should do, executing my excel test but apparently travis isn't. 

What do I need to change in Built.Scala to get tests in benchmark project executed automatically by travis???

Thanks for help.

Hope this tests helps to reproduce this issue because I'm still unable to get this error on my box...
