I'm currently trying to find out how a child build can query the build key of the parent build which has triggered the child build. While searching the net I've found this Jira Issue which looks promising to answer my question.
Since I don't have access to the linked Support Jira Issue I'd like to ask if someone could comment the available $
variables to this Jira issue. Or can I find the available variables elsewhere? So far my search wasn't successful.. Thanks!
