Compatibility Matrix

All SCM providers currently require the native executable to be installed on the server where the Sonar analysis will run. For example, for projects hosted on a Subversion repository and analysed on a Jenkins server, svn executable must be available on the Jenkins server (and its slaves if any).

(tick) - supported

(star) - tested by users

(error) - not implemented


This plugin collects SCM information on each source file to display in the source code viewer the last committer on lines.


  1. Install the SCM Activity plugin through the Update Center or download it into the SONAR_HOME/extensions/plugins directory
  2. Restart the Sonar server


Configuring the SCM Activity Plugin

  1. Set the SCM URL of your project (see SCM URL Format): sonar.scm.url properties. For Git, SVN and Mercurial, the SCM provider is automatically discovered, so what's defined in this property is not taken into account.

  2. At project level, go to Configuration > Settings > SCM Activity and specify User (sonar.scm.user.secured) and Password (sonar.scm.password.secured) if needed; if specified then developerConnection will be used, otherwise connection.
  3. Launch a new quality analysis and the metrics will be fed.




The first analysis of a project with version 1.4 will last longer than the subsequent analyses.

Forcing the Retrieval of Blame Information

In some cases, it is necessary to retrieve blame information on files that have not been changed (for example when a user has been renamed). To force this retrieval, here are the steps to follow:

  1. Deactivate the SCM Activity plugin: sonar.scm.enabled = false
  2. Run a Sonar analysis on your project
  3. Reactivate the SCM Activity plugin: sonar.scm.enabled = true
  4. Run a Sonar analysis on your project



Note that a property should be added sooner or later to explicitly force this retrieval or not. See SONARPLUGINS-2359.

Known Issues and Limitations

Subversion "Server certificate verification failed: issuer is not trusted"

Add following to .subversion/servers:

CVS anonymous access not working "org.apache.maven.scm.ScmException: password is required."

Try to set empty password for repository in .cvspass. For example:

I use Git and the annotated sources sometimes display a wrong/old author name

The plugin uses 'git blame' command to find out the author of each line. Because a user can commit with different author name/email, it is advised to have a .mailmap file at the root of the repository. This file is used by 'git blame' to find out canonical name/email of each user.
