RE: [mylyn-dev] Programmatically querying Jira using mylyn

["Mik Kersten" <beatmik@xxxxxxx>]

Hi Stefanos,

(moving this discussion to mylyn-integrators)

While we have generic facilities for querying, we do not have generic
facilities for you to specify a query because the query specification tends
to be very connector specific (e.g. JIRA's filter definition which know
about JIRA-specific attributes).  To support what you are after we would
either need a generic way of specifying queries (hard, and questionable
utility) or for you to have a String-based or otherwise externalizable
specification of the query parameters.  We are already investigating support
for the latter for generic duplicate detection:

  197181: make duplicate detection support generic
  https://bugs.eclipse.org/bugs/show_bug.cgi?id=197181

If you could describe your use case we could figure out how to better
support this kind of generic creation.  As an additional example check out
how BugzillaQueryTest runs headless, since it has considerably less
coupling, there are also some slightly out-of-date docs here and it would be
great if you could add some notes on your experiences with JIRA to that:
