Git plugin for Jenkins: How do I set env variables GIT_AUTHOR_EMAIL and GIT_COMMITTER_EMAIL?

Question

I have been trying to set the environment variables GIT_AUTHOR_EMAIL and GIT_COMMITTER_EMAIL so that the GIT plugin for Jenkins claims to be setting(https://wiki.jenkins-ci.org/display/JENKINS/Git+Plugin).

I see that the rest of the environment variables viz. GIT_URL, GIT_BRANCH, GIT_COMMIT, GIT_PREVIOUS_COMMIT are set accurately for each of the jenkins jobs.

I am testing this by printing out all the environment variables in a jenkins jobs shell script build step by using printenv.

Can somebody please let me know if I am missing something here ? Here are few of the possible reasons that I could think of..

1. Bug with the plugin
2. Issue with Jenkins setup/config
3. Issue with GIT config in Github..

Please help me in this regard.

Thanks!

p.s. I also saw a similar question is left unanswered (Github-plugin for Jenkins get committer and author name)

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.
