About Jenkins

Jenkins is a continuous integration (CI) server. It is in use on Eclipse servers for Eclipse projects as part of the Common Build Infrastructure (CBI). This page is about the hosted service at For more information on the project itself, or to download Jenkins, please see the Jenkins project page.

Since Hudson is not maintained anymore, Jenkins is the replacement for it. They share a common ancestry, but have diverged in the past. Eventually all Hudson Instances Per Project (HIPP) will be completely replaced by Jenkins Instances Per Project (JIPP). The migration will be slow in the beginning, to minimize risks and impact on the running build infrastructure (see HIPP2JIPP migration)

General Information

Jenkins instances are maintained by the Eclipse Webmasters/Release Engineer. The Jenkins CI servers are available here:

Asking for Help

Requesting a JIPP instance

Please file a bug against Eclipse Foundation > Community > Hudson to request your project's own instance. Please ensure your project lead can +1 the request. Please specify if you wish to grant write access to your download or code repositories.

About write access
If your git repo is handled by Gerrit, granting write access to your code repositories is a different procedure, so you must ask specifically for it. If you don't use Gerrit, then granting write access to your download area automatically grants write access to your code repositories and vice-versa.

Security issues
There may be security issues related to using the Gerrit plugin and there may be security issues related to allowing the CI system to write directly to your code repos and downloads area. If you request plugins other than those available on the Shared instance, webmaster may not be able to help troubleshoot any issues that you may encounter with your instance.

Jenkins hardware

Jenkins instances run on SLES12 SP1 x86_64 host machines, with 64GB RAM (hipp1 & hipp2) or 128GB RAM (hipp3-10).

Jenkins configuration and tools

Check CI best practices for general recommendations how to setup Jenkins.

Tools (and locations)

Build tools like JDK, Maven, Ant and Gradle are already configured in every Jenkins instance.

  • JDK
    • jdk9-latest (/shared/common/jdk-9_x64-latest)
    • jdk1.8.0-latest (/shared/common/jdk1.8.0_x64-latest)
    • jdk1.7.0-latest (/shared/common/jdk1.7.0-latest)
    • jdk1.6.0-latest (/shared/common/jdk1.6.0-latest)
    • jdk1.5.0-latest (/shared/common/jdk1.5.0-latest)
  • Maven
    • apache-maven-latest (/shared/common/apache-maven-latest)
    • apache-maven-3.0.5 (/shared/common/apache-maven-3.0.5)
  • Ant
    • apache-ant-1.9.6 (/shared/common/apache-ant-1.9.6)
  • Gradle
    • gradle-latest (/shared/common/gradle-latest)
    • gradle-3.1 (/shared/common/gradle-3.1)


Since April 2017 the proxy is no longer required to access the internet from JIPP instances. Currently outbound connections are limited to ports 80 and 443 by the firewall so there are still some restrictions.

Setup for specific plugins

GitHub Pull Request Builder Plugin

The GitHub Pull Request Builder Plugin (GHPRB) allows to build/test pull requests and provide immediate feedback in the pull request on GitHub.

To set this up, please open a Bugzilla issue against the Hudson component and request this feature.

Here are some details about what happens during the setup process:

  • The GHPRB plugin is installed in the JIPP.
  • Webmaster creates a GitHub bot user and adds it to the respective team on GitHub.
  • The credentials of the GitHub bot user are added to the JIPP (with user name and password, because SSH keys are not recommended/supported by the plugin).
  • The GHPRB plugin's main config is set up.

Once the ticket is resolved you should be able to configure and use the GHPRB plugin in your jobs.

Instructions how to set up GHPRB plugin in jobs can be found here:

Please note: Currently we don't recommend to use the 'Use github hooks for build triggering' option. Instead, with this option turned off, Jenkins is polling GitHub instead. Which should work just fine in most cases.

More info can be found in the GitHub readme:

Differences between Hudson and Jenkins

Hudson Jenkins
Job templates "cascading" built-in only rudimentary with plugins
Maven3 configuration Yes No
GitHub pull request builder plugin No Yes

HIPP to JIPP migration (HIPP2JIPP)

All Hudson masters will be gradually migrated to Jenkins (this should be done in late Q1-early Q2 of 2018).

We are currently improving our tooling to automate the migration. In the meantime we are migrating individual HIPPs on request. To request a migration please open a Bugzilla issue against the Hudson component. Your place in the queue will depend on the complexity of your HIPP (amount of jobs, use of exotic plugins or build configurations).

Preparations for a migration:

  • We recommend to use the migration as an opportunity to clean up your HIPP. Please check for old/deprecated build jobs that can be deleted, etc.
  • Since the "cascading job" feature of Hudson is not supported in Jenkins, such jobs will need to be converted to normal jobs first.

The following tool is used to convert the configuration XMLs to a format that Jenkins understands:

In most cases the migration should work straight-forward and configurations are converted without any problems. Nevertheless backups are created and can be made available on request if configurations are lost.
