Jenkins pipeline branch name returns null

Question

I\'m trying to get the name of my branch for a jenkins groovy script. I cannot get the current branch name. I try the following:

stage(\'Check out code\')
ch         


        

Answer 1

In the pipeline job I'm using env.GIT_BRANCH which resolves to origin/{BRANCH}

In the case of a multibranch job, env.GIT_BRANCH resolves to {BRANCH} (no origin/).

Answer 2

I had this same issue, but I resolved it by changing

println "${env.BRANCH_NAME}"

to

println "${BRANCH_NAME}"

Note my plugin is also checking out in detached mode:

git checkout -f e10a170e17fb5f9282f903a7b3cd17bd2e181dee

Answer 3

My workaround, Don't know if work for someone else..

def branchName = getCurrentBranch()
echo 'My branch is' + branchName

def getCurrentBranch () {
    return sh (
        script: 'git rev-parse --abbrev-ref HEAD',
        returnStdout: true
    ).trim()
}

Answer 4

From a simple pipeline you can use the following script:

\\...
stage('Test') {
        steps {
            script {
                branchName = sh(label: 'getBranchName', returnStdout: true, script: 'git rev-parse --abbrev-ref HEAD').trim()
                println branchName
            }   
        }
      } 
\\...

Answer 5

In Jenkins there is two pipeline options:

1. New Item -> Pipeline --> env.BRANCH_NAME return branch null
2. New Item -> Multibranch Pipeline --> env.BRANCH_NAME return branch master or branch name

Answer 6

This variable only works in a multibranch pipline:

BRANCH_NAME For a multibranch project, this will be set to the name of the branch being built, for example in case you wish to deploy to production from master but not from feature branches.

I was testing in a normal pipline
