Thank you for all of your input on this feature. I'm happy to close this issue and announce that smart commits is now available for Bitbucket Server.
If you have Bitbucket Server 4.2.0+ and JIRA 7.1 you can now log time, comment on an issue, and resolve an issue in the same way you can for Fisheye or Bitbucket Cloud. You can find all the details here.
Original request description:
I'd like to see the smart commits feature as it is in FishEye.
If the whole feature is too much to bite off, at least the #time, #comment and #resolve commands would be nice.
I've found this feature a great way of breaking down barriers to keeping our Jira projects properly updated.
