title: Disable Sonar duplications on Entity, DTO packages
body: <p>Is there any way to disable certain metrics from selected packages in Sonar? I use Sonar to analyze my project and in Entity and DTO packages I have some code that is equal - the same field ID with annotations, etc is being reported as a duplication by Sonar. It has absolutely no sense to me so I'd like to disable it. How can I achieve this? Using the global exclusions option disables all metrics on selected package but how to do it just for code duplications?</p>
