Creating Bitbucket pull requests doesn't always build in Bamboo

We are using Bamboo 6.4.1 and Bitbucket 5.9 we have bamboo setup to auto-build when Pull requests are made into our development branch.  This works great most of the time, but sometimes it will not run the build.   Sometimes opening/closing the pull request will trigger the build but other times it won't no matter what we do.

We aren't sure why this is happening or what is going on but it is extremely annoying.  Is there something I can look at it in the logs etc. to dig into why this is happening?  Thanks!

Hi Joel,

I'll list below the expected behavior so you can check in Bamboo logs what exactly is happening:

If the Branch the branch doesn't exist in Bamboo and the branch detection is set to only create the branch plan only when a pull request is created.

  • When a new branch is created, bitbucket will call the "stash-pullrequest-opened-remote-event" endpoint:
2018-06-07 15:50:05,391 INFO [http-nio-8085-exec-25] [AccessLogFilter] POST http://bamboo:8085/rest/remote-event-consumer/latest/events/stash-pullrequest-opened-remote-event 577869kb
  •  The new branch will be created in Bamboo:

  • The first build for the plan branch will be dispatched:

  • When the branch is merged, bitbucket will the "stash-pullrequest-merged-remote-event" endpoint:

  •  The change will be detected and a build for the "master" branch will be dispatched:
2018-06-07 17:42:16,458 INFO [10-BAM::PlanExec:pool-16-thread-2] [ChangeDetectionListenerAction] : Change detection found 2 changes for plan PROJ-PULL
2018-06-07 17:42:16,714 INFO [10-BAM::PlanExec:pool-16-thread-2] [ChainExecutionManagerImpl] Build PROJ-PULL-JOB1-2 has been dispatched


Could you please analyze the logs and let us know which of these events are not being executed? 

If the changes are not being detected, could you please double check if you're not using the same repository URL with a different "repository type" (e.g. Git)? There is a possibility that a second repo is updating the Git cache before the merge and that can cause Bamboo to "think" no changes were made.

Hey I have the same problem and sometimes it only logs the first message and sometimes it continues to the other actions. Can you maybe help me ?
