Can anyone explain me why we need SCM Plugin in Sonar Qube what are the benefits of it.I tried to find the same solution on below link:- 1. http://docs.sonarqube.org/display/PLUG/SCM+Activity+Plugin 2. http://docs.sonarqube.org/display/SONAR/SCM+support
But did not get much knowledge about it.
You don't need the SCM Activity Plugin; the core functionality to support SCM data was rolled into the platform in 5.0.
You do need the plugin that corresponds to your SCM engine. It provides the specific integration between your SCM's commands and the SonarQube server. That is, it actually talks to your SCM to get the commit data for each line of each file and puts it in a format SonarQube can understand.
