Bitbucket Cloud
The TeamCity integration with the Bitbucket Cloud issue tracker can be set up separately, or as a part of TeamCity integration with Bitbucket Cloud as a source code hosting service.
When setting up integration with the Bitbucket issue tracker, in addition to the repository URL and other general settings, you need to configure authentication and specify the issue ID pattern.
Authentication
TeamCity allows you to select whether you want to connect to the Bitbucket issue tracker anonymously or to authenticate via username/password.
tip
For Bitbucket Cloud team accounts, it is possible to use the team name as the username and the API key as the password.
Converting Strings into Links to Issues
You also need to specify which strings should be recognized as references to issues in your tracker. For Bitbucket, you need to use the regex syntax, for example, #(\d\+).
TeamCity will resolve the issue number mentioned in a VCS comment and will display a link to this issue in the web UI ( for example, on the Changes Page, Issues tab of the build results page).
