It's possible, but it's not easy.
You'd have to write your own global push hook, similar to Yet Another Commit Checker's global hook.
In your hook's onReceive() method you would extract JIRA ticket references from the commit messages, and then use Bitbucket's built-in JIRA index to see if any previous commits already referenced them.
private final com.atlassian.bitbucket.idx.CommitIndex commitIndex;
In particular, you would call the CommitIndex.findByProperty() method to see if any commits in any repos referred to the given JIRA ticket:
String jiraKey = "TKT-123";
PageRequest pr = new PageRequestImpl(0, 999);
pageResult = commitIndex.findByProperty(
JiraConstants.IDX_PROP_ISSUE_KEYS, jiraKey, false, pr);
Note: a naive implementation of this would potentially block all new commits that referenced "UTF-8" or "ISO-9000", since Bitbucket assumes those are JIRA tickets. Bitbucket does not check if a given "ticket-like" string in a commit message actually exists in your JIRA instance. It just indexes all "ticket-like" strings regardless.
As a project manager, I have discovered that different developers want to bring their previous branching method with them when they join the team. Some developers are used to performing individual wo...
