The Delivery Pipeline plugin allows for fine grained visualization of tasks within a Jenkins pipeline stage if the task pipeline step is used. However, the task specific status of a finished task is not persisted so the information is lost in case the Jenkins master requires a restart.
Example of a finished pipeline run:
However, if Jenkins is restarted, the whole stage is shown as failed (as the information is currently derived directly from the stage, instead of the task):
This Jira issue is aiming to address the current behavior and to provide a solution for persisting information about successfully finished pipeline tasks.
