New custom scalastyle rule

[kknd22]

We need to added a very simple custom scala rule to our sonar. Looking at Scalastyle - Custom rules, seems to be pretty straight forward to generate the custom jar.
The question is that what is the best way to feed this jar to sonar? Is it jam into the lib folder sonar-scalastyle-plugin-0.0.1-SNAPSHOT.jar ? Or there is much better way to do it?
Thanks
