As a Jenkins user, I would like to be notified if there's an attempt from a user to trigger a build but the build is not triggered so that I would be able to know if I have configured the job correctly. Scenario: User add a comment that matches a job's comment pattern, but the build is not triggered due to wrongly configured JQL filter.

As a user, I would like to get a notification when the build that has been triggered by me has failed, so that I can contact my Jenkins administrator without waiting indefinitely.

JIRA Webhooks are sending User shape at the moment that is not processed by JIRA Trigger Plugin. If this information is parsed and injected via Jenkins environment variables, the following actions can then be done in Jenkins:

• User shape contains the user email address that can be freely used in Jenkins build step to send email.
• User shape contains the username that can be used for adding a JIRA comment with the user tagged e.g. by using JIRA Issue Updater Plugin.
