Automatic Synchronization
Since a JQL keyword is meta-data for an issue that has been evaluated and saved prior to a JQL search, there must be a way to keep those keywords up-to-date with the data contained in the issues. This is done automatically using system event listeners. The keywords get updated when the corresponding of following events are triggered for an issue:
Issue created event
Issue updated event
Issue deleted event
Issue link created event
Issue link deleted event
Issue commented event
Issue comment updated event
Issue comment deleted event
For example, the issue link keywords will be updated when a issue link created/updated event is triggered.
Manual Synchronization
When Power Scripts for Jira is first installed no keyword data has been applied to any of the issues. Some issues may already be completed and therefore will not trigger any events. In order to populate the keyword data for these issues you will need to run a manual synchronization. This is an intensive process that will update every single issue in Jira Cloud. This process can take some time so please be patient and allow a few hours (just to be safe) for this process to complete. We'll keep you informed on how the process is going. It should not be necessary to run this process again since each issue will get automatically updated going forward.
