Summary

Integrates Jenkins with Perforce SCM Repositories.

Plugin Information
Distribution of this plugin has been suspended due to unresolved security vulnerabilities, see below.

The current version of this plugin may not be safe to use. Please review the following warnings before use:

This plugin is very old and not very well maintained anymore. It's recommended that you use the official plugin from Perforce instead: P4 Plugin

With this plugin you can use a workspace (aka Clientspec in Perforce speak) that will synchronize files to the Jenkins workspace. At the moment, this plugin supports:

Polling
Synchronizing
Browsing latest changes
Labeling builds (tagging)

If polling is enabled, the plugin will automatically sync to the latest revision when new changelists are found. This will also trigger a new build. Also, whenever a new build is triggered manually in Jenkins, the plugin will sync to the latest revision in the Perforce depot.

Requirements

The plugin requires that the command line client p4 is installed on the machine running Jenkins.

Usage

Allow the plugin to communicate with Perforce...
1. Either create a new user or use an existing "daemon" type user
  - Note: This "daemon" user must be logged in prior to configuring or running builds with Jenkins. And you must not specify the P4CLIENT environment variable because this will overwrite anything that Jenkins is trying to do.
2. Create a workspace (clientspec) for the plugin to use. Name it "jenkins-jobname" or something.
3. Ensure that the workspace matches your development settings for your project (e.g., LineEnd, Options, etc.)
4. Important Note: If you will be concurrently building multiple projects from Perforce, it would be best to create a Perforce workspace for each project.
Install the plugin. Download it here.
Create a new project, under "Source Code Management," choose Perforce.
Enter your server specific details along with the information for the user that Jenkins will be using for polling/syncing. If you are familiar with Perforce, this all should be second nature. Remember, click on the question mark icons for context sensitive help.
Under Build Triggers, check "Poll SCM."
Save your changes and let Jenkins do its job.

Post Configuration

A new option will appear on your project's details page: "Perforce Polling Log." You can check this to see what Perforce has been up to...

Within any build for your project, a new option appears: "Label This Build." Click on this to see the following screen. Here you can create a Perforce Label allowing your team to sync to this build.

Quirks

If Jenkins's copy of the project is modified outside of Perforce (say a user deletes the entire project within the workspace directory), the builds following will likely fail. This is because the local copy is out of sync with what is in the depot. Perforce tracks what you have sync'd via the workspace and the way to bring down files that you deleted "accidentally" is to do a "force" sync. If this happens, you can use the option "One Time Force Sync" in the project configuration screen. The next time a build is triggered, p4 sync will be run with the -f option.

Perforce has specific issues when projects within a depot exist in different local locations that don't map directly to the depot. This is precisely how Jenkins operates. To get around this requirement, we have to do some non-standard things. Every build will grab the Perforce workspace and then modify it to suit the needs of the current Jenkins project. It then syncs the projects files and performs the build. This means that no two projects utilizing the same Perforce workspace should be built at the same time. It is unknown what will happen if you are synchronizing with one build, but another build attempts to modify the same Perforce workspace. It will probably be Not Good(tm). If builds must be performed concurrently, multiple workspaces can be used to get around this.

Advanced Configuration

Sync multiple builds to the same changeset

Say you have a stream of builds that need to run and you need every build to sync to the same changeset. There are a couple of ways to accomplish this. The first is to use a counter. In your job configuration for Job A, you will need to define a P4 Counter (say "projectA-counter") and check "Update counter to most recent changeset". Assuming your perforce user has sufficient privileges to create and set counters, this will check out Job A with the latest changeset, and update the counter with that changeset number. Then you can configure the rest of the jobs to use the counter "projectA-counter" and they will automatically sync to that changeset.

The alternative way is to pass the changeset through the builds as a parameter using the parameterized trigger plugin. In order to do this, you will need to dump the changeset number from the build environment into a properties file so the trigger can read it. A build step with

echo p4.changelist=$P4_CHANGELIST > change.properties

will create the properties file that can be loaded with the parameterized trigger plugin. After that it's just a matter of adding the 'p4.changelist' parameter to the downstream job, and using it in the "P4 Label" configuration field of the perforce plugin.

Note that with both these techniques, the changelog information for the downstream builds will not be available.

Version 1.3.8 "Create Workspace" breakage

In version 1.3.8 a new option was introduced to allow users the ability to disable automatic creation of clients. Unfortunately, the default for pre-existing jobs was not being correctly set. All existing jobs have this option set to false, which can cause build errors in dynamic environments.

If this has happened, and you want to set all jobs back to their original behavior, you can run the following groovy script in the jenkins script console:

hudson.model.Hudson.instance.projects.each{proj ->
  if(proj.scm instanceof hudson.plugins.perforce.PerforceSCM){
    proj.scm.setCreateWorkspace(true);
  }
};

Note that if you went from <=1.3.7 to >=1.3.9, this issue will not affect you.
