Multibranch Pipeline that includes GitHub Pull Requests

[raykr...@gmail.com]

I have a Multibranch Pipeline job that builds branches of the main repository, however I'm unclear what configuration changes I need to make in order to build and comment on GitHub Pull Requests.

I have the GitHub hooks configured (push, pull request and comment), however the job does not fire for pull request open, nor does a scan "find" the pr and build them.

Is there something I am missing in order to have a single job build it all?
What is the prescribed approach to building GitHub pull requests (requires a pipeline build i.e. Jenkinsfile)?

Jenkins: 2.32.3
Plugins:
 - Git:3.01
 - GitHub:1.25.0
 - GItHub API:1.80
 - GitHub Integration Plugin:0.1.0-rc29

 - Pipeline:2.5
 - Pipeline Multibranch:2.12

 - SCM API:2.07

You need the GitHub Branch Source plugin https://plugins.jenkins.io/github-branch-source  for the best experience.  It may not be supported on that old a version of Jenkins.  

You may also need a newer version of the git plugin, since there have been many Pipeline and Multi-branch related improvements to the git plugin since version 3.0.1.

Thanks Mark.  I am not able to upgrade Jenkins myself (a separate group manages it) but will install upgrade as much as I'm able.

You might also consider a short-lived experiment running a Jenkins instance from a Docker container.  If you don't mind a Jenkins image that has my preferred plugins, you can use https://github.com/MarkEWaite/docker-lfs/blob/lts-slim-with-plugins/Dockerfile-slim .  I admit that it is focused entirely on my own needs.  However, the list of plugins is current and meets my needs very well.

Thanks!  I'll give it a shot.  I was able to upgrade the Git plugin to 3.7 but the remaining are all gated on an underlying Jenkins upgrade, including GitHub Branch Source as you suggested.
