Supporting SCM providers

The SonarScanners use information from the project's SCM provider, if available, to:

• Assign a new issue to the person who introduced it. The last committer on the related line of code is considered to be the author of the issue.
• Estimate the coverage on new code, including added and changed code since in your new code.
• Display the most recent commit on each line in the code viewer. 

The only required SCM command is "blame", which gets the last committer of each line for a given file. This command is executed by a SonarQube Community Build plugin through the extension point org.sonar.api.batch.scm.ScmProvider. See the embedded SCM integrations documentation for more details.
