Overview

### CI Setup Ah Jenkins, so many memories. So, if you’re using Jenkins, you’re hosting your own environment.

#### GitHub You will want to be using the [GitHub pull request builder plugin](wiki.jenkins-ci.org/display/JENKINS/GitHub+pull+request+builder+plugin) in order to ensure that you have the build environment set up for PR integration.

With that set up, you can edit your job to add ‘bundle exec danger` at the build action.

##### Pipeline If your’re using [pipelines](jenkins.io/solutions/pipeline/) you should be using the [GitHub branch source plugin](wiki.jenkins-ci.org/display/JENKINS/GitHub+Branch+Source+Plugin) for easy setup and handling of PRs.

After you’ve set up the plugin, add a ‘sh ’bundle exec danger’‘ line in your pipeline script and make sure that build PRs is enabled.

#### GitLab You will want to be using the [GitLab Plugin](github.com/jenkinsci/gitlab-plugin) in order to ensure that you have the build environment set up for MR integration.

With that set up, you can edit your job to add ‘bundle exec danger` at the build action.

#### General

People occasionally see issues with Danger not classing your CI runs as a PR, to give you visibility the Jenkins side of Danger expects to see one of these env vars:

  • ghprbPullId

  • CHANGE_ID

  • gitlabMergeRequestIid

  • gitlabMergeRequestId

### Token Setup

#### GitHub As you own the machine, it’s up to you to add the environment variable for the ‘DANGER_GITHUB_API_TOKEN`.

#### GitLab As you own the machine, it’s up to you to add the environment variable for the ‘DANGER_GITLAB_API_TOKEN`.
