Create git tag from within Jenkins pipeline script

Question

Within my Jenkins pipeline script, I would like to do something like this:

sh("git tag ${BUILD_NUMBER}")

However, this wouldn't work if git isn't found on the shell.

Is there any Jenkins plugin that can do this from a Jenkins pipeline script?

Answer 1

There is no plugin support for this currently but might be in the future:
https://issues.jenkins-ci.org/browse/JENKINS-28335

While you go over this Jira issue take a look at Andrey Makeev's temporary solution. also documented here.

Answer 2

Here's how I do it, where shell and Version are custom functions and class, respectively, and shell is a drop-in replacement for the sh function:

    void gitTag(Version releaseVersion) {
      sshagent(['devops_deploy_DEV']) {
        shell 'git tag -d \$(git tag)'
        shell 'git fetch --tags'
        echo "New release version ${releaseVersion.normalVersion}"
        shell "git tag -fa ${releaseVersion.normalVersion} -m 'Release version ${releaseVersion.normalVersion}'"
      }
    }
