Currently in https://github.com/jenkinsci/adobe-cloud-manager-plugin/blob/13792131db919014eb26b34821f0e8ebe5430094/src/main/java/io/jenkins/plugins/cloudmanager/CloudManagerBuilder.java#L93 there is no exception handling in case execution is already running.

Usually what is desired is to try to cancel the current execution and then trigger a new execution.
