I installed latest Jenkins (2.150.1) with latest plugins (including Bitbucket Branch Source Plugin 2.4.0).

I defined my Bitbucket project to be scanned.

Initial scan is performed, all repositories are found, latest commit per branch per repository is found).

Later I commited a change to one of the branches. The plugin is supposed to find change and if Jenkins file exist kickstart a pipeline. It doesn't.

 

I added the following pipeline to reindex the branches per repository for my Bitbucket Branch Source job.

it is executing on a one minute interval and  temporary solving the plugin malfunction.

node

{ Jenkins.instance.items .find \{ it.name == 'My_bitbucket_branch_source_job' }

.items
.each

{ echo 'in the loop' echo it.name it.indexing.run() }

}
