Description:

After updating the Bitbucket Branch Source Plugin to 936.4.4, Jenkins fails to send build status notifications to our Bitbucket Server 7.0 instance (non–Data Center license).

The error shows the plugin:

{{[Bitbucket] Notifying commit build result
ERROR: Could not send notifications
java.io.FileNotFoundException: Resource http://<redacted>/rest/api/1.0/projects/BENCH/repos/fabric/commits/8eeb1fc3a8c662fd77451e6a3c1f24e97360e63a/builds not found}}

This worked fine in previous plugin versions (e.g., 922.va_71d0e0b_7b_8d).
After upgrading, all jobs fail to send commit build statuses back to Bitbucket.

Environment:

• Jenkins: 2.504.1 (LTS)

• Bitbucket Server: 7.0.0 (Server license, not Data Center)

• bitbucket-branch-source-plugin: 936.4.4 (failing)

• bitbucket-branch-source-plugin: 922.va_71d0e0b_7b_8d (working)

• OS: AlmaLinux

• Java: 21.0.7+6-LTS

Steps to Reproduce:

1. Use Jenkins with Bitbucket Server 7.0 (non–Data Center).

1. Upgrade bitbucket-branch-source-plugin to 936.4.4.

1. Run a multibranch pipeline job linked to Bitbucket Server.

1. Observe notification attempt in build logs.
