How do I achieve git Additional Behaviors => Checkout to specific local branch in Jenkins pipeline?

check this one http://your-Jenkins:8080/pipeline-syntax/ , you can have samples of all your installed plugins.

checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [[$class: 'RelativeTargetDirectory', relativeTargetDir: 'your-sub-directory']], gitTool: 'Default', submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'd767bb7a-4c1e-4654-a310-996d4ece5b02', url: 'git@github.com:yyy/xxx.git']]])
