Multibranch Pipeline Project

The Multibranch Pipeline project module handles creating Jenkins workflow projects. You may specify multibranch in the project-type attribute of the Job definition.

Multibranch Pipeline implementantion in JJB is marked as experimental which means that there is no guarantee that its behavior (or configuration) will not change, even between minor releases.

Plugins required:

Configure BitBucket scm

Requires the Bitbucket Branch Source Plugin.

Parameters:
  • credentials-id (str) – The credential to use to scan BitBucket. (required)
  • repo-owner (str) – Specify the name of the Bitbucket Team or Bitbucket User Account. (required)
  • repo (str) – The BitBucket repo. (required)
  • discover-tags (bool) – Discovers tags on the repository. (default false)
  • server-url (str) – The address of the bitbucket server. (optional)
  • head-filter-regex (str) – A regular expression for filtering discovered source branches. Requires the SCM API Plugin.
  • discovery-branch (str) – Discovers branches on the repository. Valid options: ex-pr, only-pr, all. Value is not specified by default.
  • discover-pr-origin (str) – Discovers pull requests where the origin repository is the same as the target repository. Valid options: mergeOnly, headOnly, mergeAndHead. Value is not specified by default.
  • discover-pr-forks-strategy (str) – Fork strategy. Valid options: merge-current, current, both, false. (default ‘merge-current’)
  • discover-pr-forks-trust (str) – Discovers pull requests where the origin repository is a fork of the target repository. Valid options: contributors, everyone, permission or nobody. (default ‘contributors’)
  • build-strategies (list) – Provides control over whether to build a branch (or branch like things such as change requests and tags) whenever it is discovered initially or a change from the previous revision has been detected. (optional) Refer to ~build_strategies.
  • local-branch (bool) – Check out to matching local branch If given, checkout the revision to build as HEAD on this branch. If selected, then the branch name is computed from the remote branch without the origin. In that case, a remote branch origin/master will be checked out to a local branch named master, and a remote branch origin/develop/new-feature will be checked out to a local branch named develop/newfeature. Requires the Git Plugin.
  • checkout-over-ssh (dict) –

    Checkout repo over ssh.

    • credentials (‘str’): Credentials to use for
      checkout of the repo over ssh.
  • filter-by-name-wildcard (dict) –

    Enable filter by name with wildcards. Requires the SCM API Plugin.

    • includes (‘str’): Space-separated list
      of name patterns to consider. You may use * as a wildcard; for example: master release*
    • excludes (‘str’): Name patterns to
      ignore even if matched by the includes list. For example: release*

  • do-not-fetch-tags (bool) - Perform a clone without tags
    (default false)
  • submodule (dict)
    • disable (bool) - By disabling support for submodules you can still keep using basic git plugin functionality and just have Jenkins to ignore submodules completely as if they didn’t exist.
    • recursive (bool) - Retrieve all submodules recursively (uses ‘–recursive’ option which requires git>=1.6.5)
    • tracking (bool) - Retrieve the tip of the configured branch in .gitmodules (Uses ‘–remote’ option which requires git>=1.8.2)
