As best I can tell there's no DIRECT (i.e. via JQL) to query against things like "Sprint.EndDate" (which is accessible via the JQL Excel plugin).
So I'm posing this to see if anyone has any ideas as to how one would be able to resolve the following query:
All Issues RESOLVED, where the END DATE of the SPRINT for each issue belongs to, happens to fall between 2 dates.
Perhaps this logic might help
Issue.Resolved is not EMPTY AND
Issue.Sprint.End_Date >= Date_A AND
Issue.Sprint.End_Date <= Date_B
If there is some way that this can be achieved without having to resort to REST API, that would be most ideal
