Currently build, by default, is configured to support Scala 2.10, thus just
executing the build works.
In order to build with Scala 2.11, you need to execute:
```
./dev/change_scala_version.sh 2.11
mvn ..... -Pscala2.11
```
Without that, it won't and should not work, because the dependencies will
try to match the ones built for the scala version being used.
