Sonar Eclipse provides a comprehensive Sonar integration for Eclipse. The objective of this Eclipse plugin is that developers do not have to leave their favorite IDE to get valuable information on code quality. Most of the information displayed in the Sonar Web interface is now available in Eclipse. Sonar Eclipse takes care to automatically collect information from the Sonar Web server and decorates the source code on-the-fly.

Installing Sonar Eclipse is pretty simple. For instructions, prerequisites and a demonstration video go to Installing Sonar Eclipse.

Table of content


  • Get quality measures on ressource (project, package and files)
  • Get hotspots on given metrics (files with most duplicated lines, most complex files...)
  • Displays markers on source code upon violation of a coding standard
  • Get comprehensive list of violations on a resource
  • Bridge to Sonar Web server for access additional services (clouds, treemap...)

Configure Sonar Eclipse

Sonar Eclipse is pre-configured to access local Sonar server listening on http://localhost:9000/. To use an other address, you need first to define this server by using the Eclipse global Preferences window :

Once Sonar server is defined, the next step is to "link" eclipse projects with projects defined and analysed in Sonar server(s). This linkage operation can be done by right-clicking on the the project into the "Package explorer", and then by choosing "Configure -> Associate with Sonar..." :

You are now all done with configuration and can start using Sonar Eclipse.

Use Sonar Eclipse

Sonar Eclipse provides one eclipse perspective and four eclipse views. Those eclipse views can of course be used outside the "Sonar" eclipse perspective, but this tutorial described the default "Sonar" eclipse perspective layout.

To activate the "Sonar" eclipse perspective, click on "Windows -> Open Perspective -> Other ..." and select "Sonar" :

Measures view

The Measure view allows to get all available measures on the selected ressources. Most of the time, developers focus their attention on only few important metrics like complexity, uncovered lines of code by unit tests, duplicated lines, ... and want to get a quick overview on those metrics. That's why favourite metrics are displayed on the top of the Measures view. Adding or Removing a metric from the favourites list is made possible by right clicking on the metric name :

Violations view

The Violations view displayed the list of all violations to quality rules for the selected ressources (project, package, file) :

A double-click on a violation open the source code editor and highlight the violation :

Once a violation has been fixed, you can simply delete it by clicking on the violation icon and then by selecting the "Delete violation" item. Deleting a violation also removes it from the Violations view :

Hotspots view

The Hotspots view allows to quickly identify hotspots (files) according to favourite metrics (defined in the Measures view). You can for instance look for files with the greatest number of duplicated lines, greatest number of violations, greatest number of uncovered lines by unit tests, ... :

Web view

The Web view displays the web Sonar dashboard (for projects and packages) or the web Sonar ressource viewer (for files). This web page could be used to access quality information or tools (like clouds, treemap, ...) that are not yet natively available in Sonar Eclipse :
