Build Status Build Status Release

A plugin for Jenkins to capture and visualize code coverage testing results for projects using the JaCoCo for code-coverage analysis.

More information can be found on the Wiki page

Note: Version 2.0.0 and higher requires using JaCoCo 0.7.5 or newer, if your projects still use JaCoCo 0.7.4, the plugin will not display any code-coverage numbers any more! In this case please use version 1.0.19 until you can update jacoco in your codebase.

Looking for ways to contribute?

When looking for things to work at there are pull requests and a list of Jenkins Issues.

Discussion list

There is a developer list at!forum/jenkins-jacoco-plugin-mailing-list, it is usually very low volume.

Contributing to the Plugin

Plugin source code is hosted on GitHub.

New feature proposals and bug fix proposals should be submitted as GitHub pull requests.

Fork the repository on GitHub, prepare your change on your forked copy, and submit a pull request (see here for open pull requests). Your pull request will be evaluated by the Cloudbees Jenkins job and you should receive e-mail with the results of the evaluation.

Before submitting your change, please assure that you've added a test which verifies your change. There have been many developers involved in the jacoco plugin and there are many, many users who depend on the jacoco-plugin. Tests help us assure that we're delivering a reliable plugin, and that we've communicated our intent to other developers in a way that they can detect when they run tests.

Code coverage reporting is available as a maven target and is actively monitored. Please try your best to improve code coverage with tests when you submit.

Before submitting your change, please review the findbugs output to assure that you haven't introduced new findbugs warnings.
