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.

Answer 1

The simplest way to fetch the Git variable in Jenkins through Jenkinsfile

node {
  def scmVars = checkout scm
  echo 'scm : the commit id is ' +scmVars.GIT_COMMIT
  echo 'scm : the commit branch  is ' +scmVars.GIT_BRANCH
  echo 'scm : the previous commit id is ' +scmVars.GIT_PREVIOUS_COMMIT
  def commitEmail = sh(returnStdout: true, script: "git --no-pager show -sformat=\'%ae\'")
  echo " the commiter email is'${commitEmail}'"
  def commitName = sh(returnStdout: true, script: "git --no-pager show -s format=\'%an\'")
  echo " the commiter name is'${commitName}'"
}

In console you will get the

GIT_COMMIT:
GIT_BRANCH:
GIT_PREVIOUS_COMMIT:
commitEmail:
commitName:
