any issues created on Bitbucket doesn't appear on JIRA. It's the same, when I create issue on JIRA, it doesn't appear on BitBucket
What should I have wrong? Thanks
The linking between JIRA and Bitbucket does not copy Bitbucket issues over to JIRA, or vice versa. The intention is that you use either JIRA, or the Bitbucket issue tracker.
For those using JIRA, the DVCS Connector makes it so that whenever you mention a JIRA issue in a commit message, comments, etc, Bitbucket will make it a link to your JIRA instance. However, you'll still want to turn off the Bitbucket issue tracker. It's a separate thing from JIRA.
