This plugin allows you to capture code coverage reports from OpenClover - a free and open source tool based on source code of Atlassian Clover. Jenkins will generate and track code coverage across time. This plugin can be used without the need to modify your build.xml.


  1. Install Jenkins Clover Plugin.
  2. Install clover.jar in Ant's classpath (since Jenkins Clover Plugin 4.10.0).

Automatic integration for Ant builds

Clover can be integrated into Ant-based builds without the need to modify the build.xml (star) . Simply check the "Automatically record and report Code Coverage" checkbox in the Job configuration screen.

The Clover plugin will add an Ant build listener and appropriate configuration parameters to allow Clover HTML, XML, JSON and Historical reports to be generated for your Job.

These will automatically be linked to from the Job and Build pages.

(star) It works for typical build configurations in which unit tests are launched after compilation. In case you spawn processes, run in-container tests, deploy application to another machine etc then the automatic integration will not be sufficient and you'll have to set up integration manually.

Viewing the report

As soon as build is finished, click on the "Clover HTML report" link to display the code coverage report.

Jenkins 1.641 introduced content security policy, which blocks any active content in published artficats. As a result, when you click on the link, it will display the "Loading dashboard.html..." message instead of the report. In order to fix it, you must relax the policy to allow JavaScript, CSS and images. See https://wiki.jenkins-ci.org/display/JENKINS/Configuring+Content+Security+Policy for more details.

Clover documentation

We recommend reading the official OpenClover Documentation home page - you will find instructions how to integrate Clover with Ant, Maven, Grails and other tools.

In case of trouble, you may have a look at the Atlassian Community page (questions tagged 'clover').

Manually configuring the Clover plugin

  1. Install the Clover plugin
  2. Configure your project's build script to generate Clover XML reports
  3. Optional: Configure your project's build script to generate clover HTML or PDF reports (this plugin prefers HTML reports to PDF).  The plugin will not extract any information from these reports, but will use them as a better formatted most recent coverage report when they are available.
  4. Enable the "Publish Clover Coverage Report" publisher
  5. Specify the directory where the clover.xml report is generated.
  6. Optional: Configure the coverage metric targets to reflect your goals.

Configuring with Jenkins Workflow/Pipeline jobs

As of version 4.6.0 (and later) of the plugin:

node {
  git 'https://github.com/recena/maven-helloworld'
  sh "mvn clean clover:setup test clover:aggregate clover:clover"
    $class: 'CloverPublisher',
    cloverReportDir: 'target/site',
    cloverReportFileName: 'clover.xml',
    healthyTarget: [methodCoverage: 70, conditionalCoverage: 80, statementCoverage: 80], // optional, default is: method=70, conditional=80, statement=80
    unhealthyTarget: [methodCoverage: 50, conditionalCoverage: 50, statementCoverage: 50], // optional, default is none
    failingTarget: [methodCoverage: 0, conditionalCoverage: 0, statementCoverage: 0]     // optional, default is none

Maven configuration with freestyle project

The clover-maven-plugin is one of the plugins that highlights an issue with how Maven 2 handles aggregator goals.

Jenkins cannot handle maven aggregator goals with the maven2 project (alpha) project type due to how this project type calls Maven. In order to obtain multi-module clover reports, you must therefore use the free-style software project project type. In any case, the Jenkins Clover Plugin does not currently support the maven2 project (alpha) project type. In order to ensure that the correct aggregated report is generated, it is necessary to invoke maven multiple times.

Short answer:


Maven2, Clover and Multimodule with a <packaging>ear</packaging> child module

The maven2 ear packaging will break if you use the clover goal at any time during the same invocation of maven if you invoke the package or later phases (as it will see artefacts without a classifier and with the clover classifier, get confused and give up)

To work around this, you should configure your root pom to include the <packaging>ear</packaging> targets only when you are not using clover... how to do this:

        <!-- list any other ear child modules here -->

The above... hack... is why it is recommended to invoke maven three times.  If you don't need this hack, you could simplify down to two invocations, i.e.

install clover:instrument | -N clover:aggregate clover:site
