How to get the BUILD_USER in Jenkins when job triggered by timer?

Question

I wanted to show the user who triggered a Jenkins job in the post job email. This is possible by using the plugin Build User Vars Plugin and the env variable

For declarative pipeline syntax, here is a quick hack, base on @Kevin answer. For declarative pipeline you need to enclose them in a node, else you will get an error/ build failure

node {
    def BUILD_FULL = sh (
        script: 'curl --silent '+buildURL+' | tr "{}" "\\n" | grep -Po \'"shortDescription":.*?[^\\\\]"\' | cut -d ":" -f2',
        returnStdout: true
        )

    slackSend channel: '#ci-cd',
          color: '#000000',
          message: "The pipeline was ${BUILD_FULL}  ${GIT_COMMIT_MSG} "

}

The output will be slack notification sent to your slack channel with the git short description
