Bamboo monitors new branches pushed to Bitbucket and accordingly creates new plan branches.
If the first build of the plan branch failed, then no responsibility is auto-assigned, so no one is notified. (Even if you manually assign the responsibility, Bamboo does not send an email to the responsible person until the next build failure. This is a separate bug reported in https://jira.atlassian.com/browse/BAM-17387)
All the subsequent build failures in the plan branch do not have responsibility auto-assigned either. So no one will get notified and actively fix them.
The auto-assign seems to only work again when someone has fixed the build failure, and then a new commit makes the next build fail.
Is there any way to configure bamboo so it can assign the responsibility to the one who committed last in the new plan branch, if the first build fails?
