@lresende You can see followings from
http://maven.apache.org/guides/introduction/introduction-to-profiles.html.
```
All profiles that are active by default are automatically deactivated when
a profile in the POM is activated on the command line or through its activation
config.
```
So once -Pscala-2.11 is defined, `scala-2.10` should be automatically
deactivated.
