Jenkins GitHub pull request builder - get branch name for execute shell

Question

I am using Jenkins GitHub pull request builder plugin for running my unit tests when a pull request is made vis a vis a web hook. For the build step, I need to know the name of the branch that is being merged in (e.g. I need develop branch if merging that into master branch). Is there a way to get access to this in the Jenkins execute shell? Thanks,

Answer 1

Your link has the answer:

The plugin makes some very useful environment variables available.

1. ghprbActualCommit

2. ghprbActualCommitAuthor

3. ghprbActualCommitAuthorEmail

4. ghprbPullDescription

5. ghprbPullId

6. ghprbPullLink

7. ghprbPullTitle

8. ghprbSourceBranch

9. ghprbTargetBranch

10. sha1

You'll want to use $ghprbSourceBranch to get the value of the branch being built somewhere else in your script.

Answer 2

In the "Branch Specifier", enter ${sha1}.
