/**
 * Build and test the kubernetes plugin using the plugin itself in a Kubernetes cluster
 *
 * A `jenkins` service account needs to be created using src/main/kubernetes/service-account.yml
 *
 * A PersistentVolumeClaim needs to be created ahead of time with the definition in examples/maven-with-cache-pvc.yml
 *
 * NOTE that typically writable volumes can only be attached to one Pod at a time, so you can't execute
 * two concurrent jobs with this pipeline. Or change readOnly: true after the first run
