Git Variables in Jenkins Workflow plugin

Question

I\'d like to access git variables such as GIT_COMMIT and GIT_BRANCH when I have checked out a repository from git further down in the build stream.

You can define your jobs (extracting git info from last commit) inside node for execution in a queue.

node {

  //Code checkout from SCM (here - `git`)
  checkout scm

  stage("GIT INFO"){
    echo ":::::::::::GIT_SHORT_COMMIT::::::::::::::::::::::::"

    GIT_SHORT_COMMIT = sh(returnStdout: true, script: "git log -n 1 --pretty=format:'%h'").trim()
    //echo in jenkins console
    echo GIT_SHORT_COMMIT
    //wanted to send these info to build artifacts, append to any file
    sh("echo ${GIT_SHORT_COMMIT} > GIT_SHORT_COMMIT")

    //Similar proceed for other git info's 
    echo ":::::::::::GIT_COMMITTER_EMAIL::::::::::::::::::::::::"

    GIT_COMMITTER_EMAIL = sh(returnStdout: true, script: "git show -s --pretty=%ae").trim()
    sh("echo ${GIT_COMMITTER_EMAIL} > GIT_COMMITTER_EMAIL-${GIT_COMMITTER_EMAIL}")



    echo ":::::::::::GIT_COMMITTER_NAME::::::::::::::::::::::::"

    GIT_COMMITTER_NAME = sh(returnStdout: true, script: "git show -s --pretty=%an").trim()
    sh("echo ${GIT_COMMITTER_NAME} > GIT_COMMITTER_NAME-${GIT_COMMITTER_NAME}")
  }

After your job is finished, you will see three additional file from above task in your workspace :

. |-- GIT_COMMITTER_EMAIL_email@gmail.com |-- GIT_COMMITTER_NAME-username |-- GIT_SHORT_COMMIT_
