In a Github PR, how to get the targeted branch name?

Is there a command to know the targeted branch name of a PR when building this PR?

Context:
I am building some code with a "Multibranch Pipeline" jenkins job.
When I create a Github Pull request, this job is triggered and I would like to know, in this job execution, what is the targeted branch name of this PR.

I have tried different commands in my Jenkinsfile but none are giving me the expected result.

If I try this: git rev-parse --abbrev-ref HEAD it gives me: HEAD

If a execute: git branch I get: * (HEAD detached at 464f73c0)

What I want to get is, for instance, master if the PR is targeting master as destination branch.

Any idea ?
Thanks for your help

  • Thanks to @Vishwanath's idea I was able to find the answer:

    In jenkins "Multibranch Pipeline" jobs, when building a PR, the targeted branch is available as an environment variable: CHANGE_TARGET
