Answer 1

I am using a Jenkins Team Project with a Multibranch Project Setup.

I previously used checkout scm command.

Now I am using the following code:

checkout([
                 $class: 'GitSCM',
                 branches: scm.branches,
                 extensions: scm.extensions + [[$class: 'CleanCheckout'], [$class: 'LocalBranch', localBranch: 'new']],
                 userRemoteConfigs: scm.userRemoteConfigs
            ])
