The current thinking is to merge this plugin into more generic coverage plugin. Help appreciated.
Configuring the Cobertura Plugin
- Install the cobertura plugin (via Manage Jenkins -> Manage Plugins)
- Configure your project's build script to generate cobertura XML reports (See below for examples with Ant and Maven2)
- Enable the "Publish Cobertura Coverage Report" publisher
- Specify the directory where the coverage.xml report is generated.
- (Optional) Configure the coverage metric targets to reflect your goals.
Configuring build tools
Here are the configuration details for common build tools. Please feel free to update this with corrections or additions.
You can either, enable "cobertura" analysis in your 'pom.xml' files or just tell Jenkins to run "cobertura" goal.
If you don't want to change your pom files, just add the goal 'cobertura:cobertura' to your Maven project in Jenkins.
If you are using a single module configuration, add the following into your pom.xml. This will cause cobertura to be called each time you run "mvn package".
Execute cobertura only from Jenkins using profiles
You can reduce the load of your developer machine by using maven profiles to execute the plugin only if you are running within Jenkins. The configuration below shows how to enable the plugin based on the information if maven was started by Jenkins.
If you are using a common parent for all Maven2 modules you can move the plugin configuration to the pluginManagement section of the common parent...
And add the plugin group and artifact to the children
Execute cobertura only from Jenkins using profiles
It is highly recommend to reduce the workload of the developers machines by disabling the cobertura plugin and only using it from within Jenkins. The following excerpt from the parent shows how to do so:
Now that your parent is only using the plugin management section if it is running from within Jenkins, you need the childern poms adapted as well:
You must first tell Ant about the Cobertura Ant tasks using a taskdef statement. The best place to do this is near the top of your build.xml script, before any target statements.
You'll need to instrument the classes that JUnit will be testing (not the test classes themselves) as such:
Here's an example call to the JUnit ant task that has been modified to work with Cobertura.
Finally, you need a task to generate the xml report, where 'destdir' is where you want the report (coverage.xml) generated.
Your cobertura.ser is generated to your module root.
srcdir is where your *.java files are located. If you use multiple modules in one build process you need to include the module name, if you use the simple srcdir parameter. It is not required to include module name if you use fileset.
Running Cobertura in gradle, copied from Piotr Gabryanczyk's post at http://piotrga.wordpress.com/2010/04/17/gradle-cobertura-integration-revisited/ and tweaked to work for gradle 1.5:
Create cobertura.gradle in the root of your project:
Apply Cobertura.gradle in your build.gradle
Either (if single project build)
Or (if multi project build)

- Fixes some issues with finding source code
Version 0.8 (20-Sep-2007)
- Works with JDK 5 as well as JDK 6 (removing JDK dependency introduced during regression fixing)
Version 0.7 (20-Sep-2007)
- Better fix of regressions introduced in 0.5
Version 0.6 (20-Sep-2007)
- Fix of regressions introduced in 0.5
Version 0.5 (20-Sep-2007)
- Now with built in source code painting! (Source code is available at the file level for the latest stable build only).
Note that the conditional coverage is the highest coverage from all the cobertura reports aggregated in each build. Thus if you have two reports and one covers only 50% of a conditional and the other covers a different 25%, conditional coverage will be reported as 50% and not the 75% that you could argue it should be!
- The trend graph now works when there are broken builds in the build history.
Version 0.4 (29-Aug-2007)
- Initial support for multi-report aggregation (may get totals incorrect if reports overlap for individual classes - I'll need to get source file painting support implemented to remove that issue. However, this is just how the files are parsed. This version will archive the files correctly so when it is fixed your history should report correctly)
Version 0.3 (28-Aug-2007)
- Fixed NPE parsing some cobertura reports generated by Cobertura version 1.8.
- Project level report should now work (except possibly when a build is in progress)
Version 0.2 (28-Aug-2007)
- Fixed problem with configuration (was not persisting configuration details)
- Changed health reporting configuration (now handles the more generic code)
- Tidy-up of reports
- Known issues:
- Project level report does not work in all cases
- Class and Method level reports should display source code with coverage if source code is available (in workspace)
Version 0.1 (27-Aug-2007)
- Initial release. Only parses xml report. Some rough edges in the UI.
