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

This is what I'm doing, based on the example provided in the Jenkins examples repo:

node {
    git url: 'https://git.com/myproject.git'

    sh 'git rev-parse --abbrev-ref HEAD > GIT_BRANCH'
    git_branch = readFile('GIT_BRANCH').trim()
    echo git_branch

    sh 'git rev-parse HEAD > GIT_COMMIT'
    git_commit = readFile('GIT_COMMIT').trim()
    echo git_commit
}

Edit you can do this shorter via

git_commit = sh(returnStdout: true, script: "git rev-parse HEAD").trim()
