If you’re using Bitbucket together with Jira, you can easily resolve a ticket in Jira by adding a #resolve in your commit comment in Bitbucket. You can resolve multiple tickets, too; just add each ticket number per line with a #resolve right next to it, for example:

JCSW-561 #resolve
JCSW-560 #resolve
JCSW-559 #resolve
JCSW-558 #resolve
JCSW-557 #resolve
JCSW-549 #resolve

You’re welcome.
