Pipeline: Multibranch2.16Minimum Jenkins requirement: 1.642.3ID: workflow-multibranch

Enhances Pipeline plugin to handle branches better by automatically grouping builds from different branches.

Automatically creates a new Jenkins job whenever a new branch is pushed to a source code repository.
Other plugins can define various branch types, e.g. a Git branch, a Subversion branch, a GitHub Pull Request etc.

See this blog post for more info:https://jenkins.io/blog/2015/12/03/pipeline-as-code-with-multibranch-workflows-in-jenkins/

A component of the Pipeline Plugin.

Notes

To determine the branch being built - use the environment variable BRANCH_NAME - e.g. ${env.BRANCH_NAME}

Changelog

2.16 (Jun 19, 2017)

  • [44848@issue] Improved properties on non-branch projects to track which properties were actually added by the step vs. configured in the UI or otherwise directly, so that it need no longer clobber the ones not touched by the step.

2.15 (Jun 01, 2017)

  • JENKINS-34561 Option to select a script name/path other than Jenkinsfile.

2.14 (Mar 10, 2017)

2.13 (Mar 03, 2017)

  • JENKINS-33273 Load Jenkinsfile (or any file requested in loadTrusted) directly from the SCM rather than doing a checkout. Requires a compatible SCM (currently Git or GitHub).
  • JENKINS-40521 Orphaned branch projects are now effectively disabled.
  • JENKINS-41146 Help text improvement.
  • API change: AbstractWorkflowMultiBranchProjectFactory implementers may now throw IOException.

One aspect of JENKINS-33273 is that you will not get an SCM changelog from a lightweight checkout of Jenkinsfile itself---only if your script actually runs checkout scm.

This behavior change can be suppressed in case of emergency using -Dorg.jenkinsci.plugins.workflow.multibranch.SCMBinder.USE_HEAVYWEIGHT_CHECKOUT=true.
