Git Checkout in Jenkins

By default, the Jenkins checkout plugin wipes the directory before checkout. This configuration allows you to checkout to a seperate directory. SSH authentication to github.

checkout([
        $class: 'GitSCM', 
        branches: [[name: '*/master']],
        extensions: [[$class: 'RelativeTargetDirectory', relativeTargetDir: 'any-directory-name']],
 userRemoteConfigs: [[credentialsId: env.SSH_CRED_ID, url: 'git@github.com:snixon/myrepo-is-awesome.git']]

Git Guide

I forgot to rebase and instead merged from the Trunk branch.

Create a patch of your Branch with all Trunk changes included, you can move those changes to a new branch. And you can rebase as needed to keep a clean commit history.

git diff Trunk Branch1 > ../patchfile
git checkout Branch2    
git apply ../patchfile
