About code quality analysis


Code quality analysis helps you to make your code:

  • less error-prone
  • more sustainable
  • more reliable
  • more readable
  • more welcoming to new contributors


Code quality analysis mainly relies on a set of tools that look at your code and give you hints. The most famous tools are Findbugs, PMD, Checkstyle; but also code coverage tools such as Jacoco. JDT itself provides very powerful quality checks, but there are not enabled by default. You should go to Error/Warnings in preferences and replace all "ignore" by "Warning". You can (and should) enable such tools in IDE.

Code quality can also be analyzed out of the IDE, running those tools and using their reports to find out the "hot spots" in your code.

About Sonar

Sonar is an open-source product which is used to gather several metrics about code quality, put them all in a single dashboard, and provide some tips to help you making your code better, more sustainable, more reliable, less bugged.

Enable Hudson Sonar plugin on your job or running mvn sonar:sonar on your Maven build will result in the following flow of actions:

  1. Sonar will locally analyze code and generate reports from many analyzers
  2. Sonar will push those reports to the Sonar dashboard

Sonar for


Sonar can be found on . Several projects already have quality reports enabled. You can drill-down on code to see Sonar annotations on each class, or navigate through the different widget on dashboard to focus on dedicated issues

Enable Sonar for your project

See . You'll need a Tycho-based build, and a Job on Hudson sandbox to be able to push reports to Sonar.

Permissions on Sonar

Sonar is currently (and will remain) public to all, but only an admin can log it. So it's not yet possible to store user preferences or be made an administrator on a project. Follow bug 391343 for more details.


Sonar is installed on a VM accessible from inside Eclipse infrastructure and with hostname sonar. It uses its embedded Jetty server to publish to HTTP, and uses a PostgreSQL database on the same VM.

The database is made accessible from servers and has a user for Sonar, and another user for Hudson. When running the Hudson Sonar plugin, the plugin uses this user to push to the Sonar database the metrics about your project.


Maintenance notes

  • Database requires to be tweak to add some "GRANT" permissions to the sonar user. Sonar could start otherwise.
  • March 2013: . Removed big log file and restarted Sonar,
  • July 2013: Got an OutOfMemory on Sonar side while running Platform-Sonar job. Increased max memory in conf/wrapper.conf and restarted Sonar.
  • July 2013: No space left on device. A lot of big memory dumps files in bin/linux-x86-64 consumed half of disk space. Removed them
  • October 2013: Migration to SonarQube 3.7.1 to provide compatibility with Maven
