Blue Ocean is available from the Jenkins update center for Jenkins 2.7.1 and above.
We use the Jenkins JIRA to log all bugs and feature requests. Create a new account, browse to JIRA and login with your account then create a new issue with the component blueocean-plugin.
It is a multi-module maven project made up of a few Jenkins plugins. There is an aggregator plugin in the "blueocean" module.
CONTRIBUTIONS ALWAYS WELCOME NO MATTER HOW BIG OR SMALL.
Some background reading: https://jenkins.io/blog/2016/05/26/introducing-blue-ocean/
This is in the main Update Center for Jenkins. Install the plugin called "BlueOcean beta" (and let it install its dependencies). The instructions here are for contributors to Blue Ocean and the morbidly curious. Expect refactoring.
Yarr...
A quick tour of some of the modules (not all). Consult README.md in respective modules for more info.
Blue Ocean Dashboard plugin. Currently contains a lot of the core of the Blue Ocean user interface and extension points. This is mostly client side JavaScript built with ES6 and React.
An aggregator plugin, making it an easy place from which to run Blue Ocean via hpi:run.
Java interfaces and classes that specify the definition of the REST API that blueocean uses. See the README.md within this module for detail on this api.
Provides the default implementation of the core REST Apis defined in the blueocean-rest plugin. It comes with only freestyle job support.
Provides implementation of Pipeline apis for Jenkins pipeline and multi-branch job types support
Core Web infrastructure that bootstraps BlueOcean UI and integrates REST API core blueocean-rest, and serves up the core javascript libraries.
At a minimum you will need a JVM, Maven and python installed, if you are doing active JavaScript development,
you may want to install NodeJS, but it is not a requirement as the frontend-maven-plugin will install
the correct version of Node locally for each plugin to build and develop with.
Builds all maven modules (run this the first time you check things out, at least)
$ mvn clean install
NOTE: If you are using macOS, you must install JDK 1.8 or the installation will fail (The most recent versions of macOS come preinstalled with JDK 10). Please follow this link for instructions.
For now, you'll need to skip the tests if building on Windows, so be sure to include the -DskipTests switch e.g.
$ mvn clean install -DskipTests
$ mvn -f blueocean/pom.xml hpi:run
Then open http://localhost:8080/jenkins/blue to start using Blue Ocean.
The Jenkins Classic UI exists side-by-side at its usual place at http://localhost:8080/jenkins.
NOTE: while running in this mode, Jenkins will automatically re-compile your JavaScript files
and LESS files for all local plugins (including those linked with hpi:hpl) where a package.json is found
that contains a mvnbuild script. If you would like to disable this behavior, you may set
the system property: -Dblueocean.features.BUNDLE_WATCH_SKIP=true
The obvious goal is for Blue Ocean to be runnable on all browsers on all platforms. We're not there yet, but getting closer. The ultimate goal will be to have browser support in line with the Jenkins Browser Compatibility Matrix.
List of browsers where we know Blue Ocean is not yet runnable:
-
Internet Explorer < 11 on Windows (the aim is to keep IE 11 working, but help is needed to maintain a Windows test environment in the pipeline)
-
AmigaOS
Follow the steps above for getting it running first.
Look in following README's for:
blueocean-restfor how to navigate the rest api.blueocean-dashboardguide on how to modify the GUI in the dashboard plugin.blueocean-rest-implfor more details on how to actively develop this plugin for backend codebases.
Blue Ocean plugins use the same plugin mechanism as Jenkins for distribution and installation, but involve a lot more JavaScript if they have GUI elements.
The best way to get started is to look at the tutorial and Yeoman starter project here: https://www.npmjs.com/package/generator-blueocean-usain The usual plugin guide also applies for Jenkins: https://wiki.jenkins-ci.org/display/JENKINS/Plugin+tutorial#Plugintutorial-CreatingaNewPlugin
Ask for help in the gitter room or on the jenkins-ux google group if you are working on a plugin.
Blue Ocean has javascript extension points that currently work with react components. This area is a work in progress, and there is no programmatic listing of all the current extension points in a plugin. However, you can grep/search for '<Extensions.Renderer extensionPoint=' and find named extension points. Plugins can contribute to these by declaring what components to plugin in those extension points in their jenkins-js-extension.yaml file (see link for a real world example - the editor implements a few extension points as react components, even css). The editor plugin is a good reference point for blue ocean plugins: blueocean-pipeline-editor.
Maven is used for most building - install Maven and JDK8 (ideally).
As npm packages are used node-gyp may be involved and this can require some tools installed to build native dependencies (native components are not used at runtime) - see https://www.npmjs.com/package/node-gyp for instructions for your platform
If you are working on the JavaScript, you will need node installed, look at the version in the pom.xml for the minimum version required.
NOTE: look in the README.md of the respective modules for more detailed dev docs.
- NOTE: after running
npm installyou will have some copies of Node you can use without installing it globally on your system, e.g. from the repository root:PATH=blueocean-web/node:$PATH npm <do-stuff> - Ensure your npm is 3.10.8+ as this release fixes some important bugs with shrinkwrap, notably #11735 in notes
- Don't edit package.json directly; use npm install to ensure that both package.json and npm-shrinkwrap.json are updated.
- To add or update a dependency:
npm install [email protected] -S -E
- To add or update a devDependency:
npm install [email protected] -D -E
- If you are handling a merge conflict in package.json, resolve the conflict in the file as normal. Then use the appropriate command to update each conflicting dependency to ensure shrinkwrap is updated.
- To remove a dependency:
npm uninstall packageName -S
- To remove a devDependency:
npm uninstall packageName -D
- If you ever need to create a shrinkwrap for the first time, use
npm shrinkwrap --devto ensure devDependencies are included in the shrinkwrap.
Full docs on npm shrinkwrap Information on building with shrinkwrap
In case you want to update your dependencies with something like npm-check-updates make sure you follow the simple steps:
ncu -a
rm -rf node_modules npm-shrinkwrap.json
npm i
npm shrinkwrap --dev
We are using prettier.js to format JavaScript in order to keep source consistent automatically rather than with build-time errors about unformatted code. We do this via a pre-commit hook, which you will have to enable in your local checkout.
- From the root directory of your
blueocean/clone, first create the symlink:
jdoe@localhost> ln -s ../../bin/pre-commit.js .git/hooks/pre-commit
- Check the symlink, because if it's wrong git will silently ignore it:
jdoe@localhost> file .git/hooks/pre-commit
# => .git/hooks/pre-commit: a /usr/bin/env node script text executable, ASCII text
- Check (with no staged changes) to make sure it's going to run successfully in your environment:
jdoe@localhost> .git/hooks/pre-commit
# => No staged files to format.
We have full i18n support in our plugins. Please read the i18n documentation on how you can provide new translations and how to work with i18n.

Watch @jenkinsci on Twitter for frequent updates and news.
If you wish to upgrade dependencies or test an upgrade to something like pipeline (as an example), pom.xml in the root of the project should have all the versions specified, a pull request to validate the changes is appreciated.
If you wanted to see if a new version of a library works with blue ocean:
- If it isn't published yet, release a beta to the experimental update center
- Open a pull request with the changes to the
pom.xmlin the root of this project (beta dependencies are fine) - Mark the pull request as "needs-review"
- Make sure to "@mention" people - @michaelneale @vivek are some good ones to start with in a pull request description
- IF the dependency being upgraded is only released to the experimental update center (ie a beta) please also mark the PR as 'DO NOT MERGE' (once it has been released to the main update center, this can be removed)
- Check back later for build success (ie unit tests)
- The Acceptance Test Harness will normally be automatically triggered after a successful PR build, however, it ie best to check it has run: (https://ci.blueocean.io/job/ATH-Jenkinsfile/job/master/) - consult a blue ocean contributor (see below) and they will ensure it has run. This is required for a dependency change.
- Contact a contributor (see below) to let them know of your proposed change so they can review it and do extra testing
- Ensure any dependencies are released to the non beta UC, before merging to master when approved.
Once the PR is accepted, it will be in use on "dogfood" on ci.blueocean.io/blue - and thus it will be in day to day use almost immediately. If it does bad things, expect to hear about it.
Contacting contributors:
Gitter is the day to day chat venue used, you can log in with your github identity.
- look for @michaelneale, @kzantow, @vivek on gitter https://gitter.im/jenkinsci/blueocean-plugin or #jenkins-ux on freenode
- Post to the mailing list: https://groups.google.com/forum/#!forum/jenkinsci-ux
The Acceptance test suite is located here: acceptance-tests
When the ATH passes and there is a consensus that a release can be performed:
- Ensure that the person doing the release has permissions for all the blueocean modules here: https://github.com/jenkins-infra/repository-permissions-updater/tree/master/permissions (or it will fail)
- Switch to the branch to release from (usually master)
- Run a
mvn clean -DcleanNode install -DskipTestsonce to clear the decks if you are working on other branches - Perform the release:
$ mvn release:prepare -DautoVersionSubmodules=true
$ mvn release:perform
This will take a while to build and upload.
- Update release notes on the wiki page
It will take a few hours to propagate to UC.
