The Sonar Runner is recommended as the default launcher to analyze a project with Sonar.


You must have previously installed the Sonar Runner and read Analyzing Code Source.


For each project a file must be created in the root directory of the project.

Then the command 'sonar-runner' must be executed from the project base directory to launch the Sonar analysis. That's it!

If a file cannot be created in the root directory of the project, there are two alternatives:

  • Either properties can be specified directly through the command line. Ex: 'sonar-runner -Dsonar.projectKey=myproject -Dsources=src1 ...'
  • Or the property 'project.settings' can be used to specify the path to the project configuration file. Ex:  'sonar-runner -Dproject.settings=../'.

Additional parameters can be defined in this project configuration file or through command-line parameters. 


If you get an java.lang.OutOfMemoryError, you can set the SONAR_RUNNER_OPTS environment variable, like this in *nix environments:

On Windows environments, avoid the double-quotes, since they get misinterpreted, turning the two parameters into a single one.
