Get git branch name in Jenkins Pipeline/Jenkinsfile

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 branch.

How do I access the branch name causing this build from the Jenkinsfile?

Everything I have tried echos out null except 

sh(returnStdout: true, script: 'git rev-parse --abbrev-ref HEAD').trim()

which is always master.

Solution

  • 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:
