Branch API PluginThis plugin provides an API for multiple branch based projects.
The following concepts are provided:
- Multibranch projects: projects consisting in a group of several projects, one for each defined branch.
- Organizational folders: a folder-like collection of Multibranch projects, one per repository.
- Branch properties: add additional information linked to the branch, which can then be used to take decisions. Some properties are provided:
- Do not trigger builds for branch.
- Do not trigger builds for organizational folder.
- Override triggering behaviour for multibranch project or organizational folder.
- Untrusted author.
- Limit builds for a branch to a certain rate.
- Discard old builds for branch.
Debug hooks for events
If you have to try and diagnose issues with events or indexing, the following information may be of assistance:
Jobs triggered by SCM Events try to capture their origin.
The origin is available as a tool-tip on the build cause:
This can be very helpful to quickly identify where events that trigger builds are coming from.
More detailed event processing information is available from the event logs.
By default, the CloudBees Folders plugin will only retain the logs of the last scan / index. If you are having issues with scanning / indexing, it can help to turn on the retention with the system property
com.cloudbees.hudson.plugins.folder.computed.FolderComputation.BACKUP_LOG_COUNT (note that you can write directly to that field using the System Groovy Console, so you can change the value on a running system without a restart)
The Multi-branch projects will log the initial arrival of events and any routing decisions in the
$JENKINS_HOME/logs/jenkins.branch.MultiBranchProject.log file (which will be rolled every 32kB, limit of 5 files)
- Once an event has been routed to a specific Multi-branch project, the responsibility for logging the event will belong with that Multi-branch project and will be stored in the
$JENKINS_HOME/jobs/$PATH_TO_PROJECT/indexing/events.log(which will be rolled every 150kB, limit of
The Organization folder projects will log the initial arrival of events and any routing decisions in the
$JENKINS_HOME/logs/jenkins.branch.OrganizationFolder.log file (which will be rolled every 32kB, limit of 5 files)
- Once an event has been routed to a specific Organization folder project, the responsibility for logging the event will belong with that Organization folder project and will be stored in the
$JENKINS_HOME/jobs/$PATH_TO_PROJECT/computation/events.log(which will be rolled every 150kB, limit of

STATUS Undeprecate the "Automatic branch project triggering" property for organization folders and disable the automated migration that replaced it with a "Named Branch" build strategy from Basic Branch Build Strategies Plugin starting in version 2.1.0 of this plugin because the migration caused an undesirable change in behavior in some cases.

- - JENKINS-56903Getting issue details... STATUS Add a health reporting metric for multibranch projects that only reports the health of the "primary" branch (as reported by the SCM)
JENKINS-56917Getting issue details...
Adds an extension point for organization folders that enabled the customization of the children of the organization folder on every organization folder scan. There are three implementations provided:
- Child Health metrics which allows controlling the health metrics that the child multibranch projects will use. Previous behaviour was to always configure just the default health metrics relevant to a multi-branch project.
- Child Scan Triggers which enabled the customization of the scan triggers for the child multibranch projects. Previous behaviour was to initially configure this to once per day and never update it. The new behaviour will now enforce the triggers defined in Child Scan Triggers for the organization folder.
NOTE if you have been using some custom hack to change the multibranch scan triggers after initial creation, that hack is no longer needed... and in fact it will now cease to work
- Child Orphaned Item Strategy which allows the child multibranch projects to have a different orphaned item strategy from the parent organization folder. By default this property will use the Inherited strategy which retains the existing behaviour but you can configure a different strategy if you want branches to be retained on a different schedule from repositories.

- Pick up API changes from SCM API 2.0 (requires SCM API 2.0.1-beta-1 and if you have either of the github-branch-source or bitbucket-branch-source plugins you must upgrade them to at least 2.0.0-beta-1)
Version 1.11.1 (Nov 04, 2016)
- JENKINS-39520 Error when dynamically installing multiple branch source plugins.
Version 1.11 (Sep 23, 2016)
- JENKINS-34564 Branch projects now get custom workspace paths inside the node’s
workspacedirectory, capped by default at 80 characters and using only ASCII letters, numbers, and simple punctuation (in particular, no
- JENKINS-37219 Added a job property for overriding the implicit branch indexing trigger flag, allowing a multibranch
Jenkinsfileto customize its own triggering behavior after the initial build.
Some projects running external processes that cannot handle even moderately long pathnames will not work with the new default workspace locations. The system property
jenkins.branch.WorkspaceLocatorImpl.PATH_MAX may be set to
0 to restore the previous behavior (which will then break some processes which cannot handle funny characters, or projects using long branch names etc.). The default value is 80; values as low as 54 (but no lower) are possible. When feasible, fix the external process to be more robust, or on Windows use
as a prefix before the remote filesystem root.
Another workaround in Pipeline scripts is to use the
ws step with an absolute pathname. You can then choose any path, and concurrent builds will still get distinct workspaces automatically; but you are on the hook for finding a valid path on the node, unrelated projects might overwrite each other’s workspaces between builds (reducing beneficial caches of SCM checkouts and the like), and the custom workspaces will not be automatically deleted if the branch project is deleted. The first problem could be avoided by using a pathname like
../custom rather than an absolute path.
Note that the
sshagent Pipeline step (SSH Agent Plugin) when used inside an
Image.inside block (Docker Pipeline Plugin) will not currently work when the workspace path exceeds 108 characters, due to a poor choice of constant in most Linux kernels: JENKINS-36997.
A full fix should probably come in JENKINS-2111 for all project types.
