Get git branch name in Jenkins Pipeline/Jenkinsfile

Question

I\'ve create a jenkins pipeline and it is pulling the pipeline script from scm.
I set the branch specifier to \'all\', so it builds on any change to any bra

Answer 1

If you have a jenkinsfile for your pipeline, check if you see at execution time your branch name in your environment variables.

You can print them with:

pipeline {
    agent any

    environment {
        DISABLE_AUTH = 'true'
        DB_ENGINE    = 'sqlite'
    }

    stages {
        stage('Build') {
            steps {
                sh 'printenv'
            }
        }
    }
}

However, PR 91 shows that the branch name is only set in certain pipeline configurations:

• Branch Conditional (see this groovy script)
• parallel branches pipeline (as seen by the OP)

Answer 2

For me this worked: (using Jenkins 2.150, using simple Pipeline type - not multibranch, my branch specifier: '**')

echo 'Pulling... ' + env.GIT_BRANCH

Output:

Pulling... origin/myBranch

where myBranch is the name of the feature branch

Answer 3

This is for simple Pipeline type - not multibranch. Using Jenkins 2.150.1

environment { FULL_PATH_BRANCH = "${sh(script:'git name-rev --name-only HEAD', returnStdout: true)}" GIT_BRANCH = FULL_PATH_BRANCH.substring(FULL_PATH_BRANCH.lastIndexOf('/') + 1, FULL_PATH_BRANCH.length()) }

then use it env.GIT_BRANCH

Answer 4

Switching to a multibranch pipeline allowed me to access the branch name. A regular pipeline was not advised.

Answer 5

A colleague told me to use scm.branches[0].name and it worked. I wrapped it to a function in my Jenkinsfile:

def getGitBranchName() {
    return scm.branches[0].name
}

Answer 6

Use multibranch pipeline.. not pipeline

In my script..

stage('Build') {
    node {
        echo 'Pulling...' + env.BRANCH_NAME
        checkout scm

    }
}

Yields...

Pulling...master
