GitHub Pull Request Builder Plugin

This Jenkins plugin builds pull requests from GitHub and will report the results directly to the pull request via the GitHub Commit Status API

When a new pull request is opened in the project and the author of the pull request isn't whitelisted, builder will ask Can one of the admins verify this patch?. One of the admins can comment ok to test to accept this pull request for testing, test this please for one time test run and add to whitelist to add the author to the whitelist.

If an author of a pull request is whitelisted, adding a new pull request or new commit to an existing pull request will start a new build.

A new build can also be started with a comment which contains, retest this please; with or without additional lines in the comment. A review summary comment will not start a new build.

You can extend the standard build comment message on github creating a comment file from shell console or any other jenkins plugin. Contents of that file will be added to the comment on GitHub. This is useful for posting some build dependent urls for users without access to the jenkins UI console.

Jobs can be configured to only build if a matching comment is added to a pull request. For instance, if you have two job you want to run against a pull request, a smoke test job and a full test job, you can configure the full test job to only run if someone adds the comment full test please on the pull request.

Installation:

Using Groovy

If you wish to configure your Jenkins master using Groovy, you can use a script such as the one below to configure the plugin:

import jenkins.model.*
import org.jenkinsci.plugins.ghprb.*

GhprbTrigger.DescriptorImpl descriptor = Jenkins.instance.getDescriptorByType(org.jenkinsci.plugins.ghprb.GhprbTrigger.DescriptorImpl.class)

List<GhprbGitHubAuth> githubAuths = descriptor.getGithubAuth()

String serverAPIUrl = 'https://api.github.com'
String jenkinsUrl = 'https://your.jenkins.url/'
String credentialsId = 'credentials-id'
String description = 'Anonymous connection'
String id = 'github-auth-id'
String secret = null
githubAuths.add(new GhprbGitHubAuth(serverAPIUrl, jenkinsUrl, credentialsId, description, id, secret))

descriptor.save()

Credentials

Creating a job:

Make sure you DON'T have Prune remote branches before build advanced option selected, since it will prune the branch created to test this build.

Parameterized Builds

If you want to manually build the job, in the job setting check This build is parameterized and add string parameter named sha1 with a default value of master. When starting build give the sha1 parameter commit id you want to build or refname (eg: origin/pr/9/head).

Job DSL Support

Since the plugin contains an extension for the Job DSL plugin to add DSL syntax for configuring the build trigger and the pull request merger post-build action.

It is also possible to set Downstream job commit statuses when displayBuildErrorsOnDownstreamBuilds() is set in the upstream job's triggers and downstreamCommitStatus block is included in the downstream job's wrappers.

Here is an example showing all DSL syntax elements:

job('upstreamJob') {
    scm {
        git {
            remote {
                github('test-owner/test-project')
                refspec('+refs/pull/*:refs/remotes/origin/pr/*')
            }
            branch('${sha1}')
        }
    }

    triggers {
        githubPullRequest {
            admin('user_1')
            admins(['user_2', 'user_3'])

            userWhitelist(['me@me.com', 'they@they.com'])
