Git Commit Message as an Environment Variable

[Jeremy Hartley]

Hi,

I'm playing around a bit with Git environment variables to send to slack and would like to include the Git commit message. I don't see it available in the list here: https://wiki.jenkins.io/display/JENKINS/Git+Plugin#GitPlugin-Environmentvariables

Is there any way to send the Git commit message to slackSend as an environment variable in my pipeline?

Thanks

Jeremy

I have a (never released) plugin that integrates with the Jenkins changelog that does something like this: https://github.com/daniel-beck/changelog-environment-plugin

If you know enough Maven to build a plugin, this might work. The problem there is that the Jenkins built-in changelog doesn't handle PRs/branches well: The first builds always have no changelogs (since there's no reference to compare them to).

But I expect it's easier and more reliable to just call e.g. git show --no-patch --format='format:%s%n%n%b' and use its output (with some extra work to get around merge commits and such, depending on exactly what you want).

You could use groovy to collect the commit message from the ChangeSet and then put it in an environment variable.

If it helps, I have an example that iterates over the changeset provided for a Pipeline job when running on a branch within a multibranch pipeline.

I believe it is limited to multibranch pipelines, but have not checked to be sure.

If GitHub is the provider there is an inprogress PR to support it:
- https://github.com/jenkinsci/pipeline-github-plugin/pull/65

Although I have not gone further to add some UTs yet though.
