Github-plugin for Jenkins get committer and author name

Question

If I understand well, git plugin exposes committer and author names and emails to environmental variables GIT_AUTHOR_NAME, GIT_COMMITTER_NAME, GIT_AUTHOR_EMAIL and GIT_COMMITTER_EMAIL based on the global configuration of git. Is there a way to get that info using Github-plugin? Does Github-plugin exposes payload info, getting from github-webhook, to environmental variables or to something else?

Answer 1

In reality these variables are available just when you overwrite the Author Name and Author Email on the Advanced features of the SCM configuration.

"Additional Behaviours" -> "Custom user name/email address"

This is described on the source code: https://github.com/jenkinsci/git-plugin/tree/master/src/main/java/hudson/plugins/git

Solution: In order to retrieve the author name and email I suggest scripting this:

GIT_NAME=$(git --no-pager show -s --format='%an' $GIT_COMMIT)
GIT_EMAIL=$(git --no-pager show -s --format='%ae' $GIT_COMMIT)

Being $GIT_COMMIT the SHA1 commit id.

Answer 2

You can use this workaround in your scripted pipeline file:

env.GIT_COMMITTER_EMAIL = sh(
   script: "git --no-pager show -s --format='%ae'",
   returnStdout: true
).trim()

Answer 3

You can try for below command, it worked for me:

git log -n 1 --pretty=format:'%ae'
