Checkout Jenkins Pipeline Git SCM with credentials?

Question

I was following this tutorial:

node {
  git url: \'https://github.com/joe_user/simple-maven-project-with-tests.git\'
  ...
}

However it doe

Answer 1

To explicitly checkout using a specific credentials

    stage('Checkout external proj') {
        steps {
            git branch: 'my_specific_branch',
                credentialsId: 'my_cred_id',
                url: 'ssh://git@test.com/proj/test_proj.git'

            sh "ls -lat"
        }
    }

To checkout based on the configred credentials in the current Jenkins Job

    stage('Checkout code') {
        steps {
            checkout scm
        }
    }

You can use both of the stages within a single Jenkins file.
