We use Jira to define user stories, and we also use Jira to manage release by tagging stories with different releases. Meanwhile we also use BitBucket and Bamboo to integrate with Jira.
When we develop the code we create branches inside our Jira card so each individual Jira has a clear view how many commits it has, how many different repos in BitBucket these commits are made to, how many PRs are still opened, how many build failed, and so on.
The release is just a group of multiple Jira stories. So the question is that is there a way I can list all commits associated with a single Release (with multiple Jira stories) or code repos impacted?
