I have a GitHub webhook triggering Jenkins when a commit is made to a branch. Jenkins is using a Multibranch Pipeline. When Jenkins runs its job it checkouts the commit which caused the webhook trigger. Additionally, available are GIT_COMMIT and GIT_BRANCH in the Jenkins environment.

I would like the Jenkins pipeline to:

• Wait until the GitHub action has completed (it builds the code and stores the binary as a job artifact)
• Jenkins to download the binary artifact for the GitHub job

The information seems to be available in the payload (value of html_url field) sent by GitHub to Jenkins, but I do not understand how to access the webhook payload in the Jenkins pipeline.

Any help appreciated on either aspect of the problem.

I have tried accessing the environment in Jenkins, and modifying the triggers in GitHub
