Jenkins : JaCoCo Plugin

Plugin Information

View JaCoCo on the plugin site for more information.

Basic information
This plugin allows you to capture code coverage report from JaCoCo. Jenkins will generate the trend report of coverage and some other statistics.

It also includes functionality to include columns in Dashboards which displays the latest overall coverage numbers and links to the coverage report.

Getting Started

The plugin provides two things, a build-publisher to record and display coverage data as part of builds as well as a new
column-type for dashboard views which can display coverage data in Dashboards.

Recording coverage for builds

Get coverage data as part of your build

First you need to get coverage calculated as part of your build/tests, see the JaCoCo documentation
for details. You need at least one or more *.exec file available after tests are executed. Usually this means adjusting
your Maven pom.xml or Ant build.xml file..

Set up coverage retrieval and publishing

In order to get the coverage data published to Jenkins, you need to add a JaCoCo publisher and configure it so it will
find all the necessary information. Use the help provided via the question-mark links for more information. Basically
you specify where the *.exec files are, where compiled code can be found and where the corresponding source code is
located after the build is finished to let the plugin gather all necessary pieces of information..

Run the job

After the job executed, the build-output will show that the JaCoCo-publisher is executed and collects the data. This
output can also give hints if something goes wrong at this stage:

[JaCoCo plugin] Loading packages..
[JaCoCo plugin] Done.
Look at results

If data gathering is successful, the build will include a link to the coverage results similar to the HTML report of
JaCoCo itself. The job page will be enhanced with a chart with the trend of code coverage over the last builds.

Coverage column

This part of the JaCoCo plugin allows you to add a new type of column to a project-table in the Dashboard view which
will show the coverage number of the last build for ajob together with some color coding which allows to quickly see
projects with low coverage.

The fill-color in use by the column is a continuous color-range with the following points:

  • PERFECT = 100.0
  • EXCELLENT at 97.0
  • GOOD at 92.0
  • SUFFICIENT at 85.0
  • FAIR at 75.0
  • POOR at 50.0
  • TRAGIC at 25.0
  • ABYSSMAL at 0.0
  • NA = No coverage configured

Build Status


  • Unfortunately JaCoCo 0.7.5 breaks compatibility to previous binary formats of the jacoco.exec files. The JaCoCo plugin up to version 1.0.19 is based on JaCoCo 0.7.4, thus you cannot use this version with projects which already use JaCoCo 0.7.5 or newer. JaCoCo plugin starting with version 2.0.0 uses JaCoCo 0.7.5 and thus requires also this version to be used in your projects. Please stick to JaCoCo plugin 1.0.19 or lower if you still use JaCoCo 0.7.4 or lower
