Hi, this code only updates in-memory config. How to trigger save to disk and trigger Job Configuration History to commit the new config?
Edit: to save the new config to disk you need to call: instance.save()

Here is how I do it:

// get Jenkins instance
Jenkins jenkins = Jenkins.getInstance()

// add cloud configuration
jenkins.clouds.add(amazonEC2Cloud)

// save current Jenkins state to disk
jenkins.save()
echo "Added new Ec2 Cloud for worker nodes: ${thisCloudname} - ${thisDescription}"
