It is really disheartening that Christian Ewald's jenkinsci/bitbucket-branch-source-plugin#106 was closed without being merged. I get it that Antonio Muñiz's concerns about being able to turn this on or off are worthwhile, but why then don't the people that use Bitbucket and git complain about not having all their closed branches?
I mean, if Jenkins itself was maintained in Bitbucket as a Mercurial repo, can you imagine having every old build for every PR branch anyone made forever? That cannot possibly be the desired default behavior. In fact, the build for Christian's branch itself is marked as an item to be deleted in the github folder on the main jenkins ci server: https://ci.jenkins.io/job/Plugins/job/bitbucket-branch-source-plugin/view/change-requests/ PR-106 may be gone from there soon because it's closed. That seems like the desired behavior!
