Someone on JENKINS-67823 commented:

This is still an issue in 2.336 for Organization Folders configured for Bitbucket Team/Project.

Had to roll back to 2.334. 

Based on my findings, that doesn't work on 2.334 either:

It appears that the bitbucket branch source plugin doesn't register the default icon properly in the first place, which now leads to the icon class being the icon source I guess?

Yeah, my previous comment outlines it well. The default bitbucket scm navigator icon is registered as "icon-bitbucket-scm-navigator" but referenced as "icon-bitbucket-scmnavigator", hence it isn't shown. I removed the regression label, because the same applies to older versions, like 2.319.3, as well:

PR is up and linked above.

Thanks notmyfault! Released as 757.vddedc5f2589a_

Still experiencing the issue with 2.337 and 757.vddedc5f2589a_ at least if a prefix is configured. Seems to be related to JENKINS-67869 which was fixed already.

Same here. Issue does not seem fixed.

That is a different issue tracked in JENKINS-67849
This issue solely tracks the typo in the icon registry of the bitbucket branch source plugin.

I have the same issue when running jenkins in a tomcat (deployed as war) - no --prefix set but exactly this behaviour (2.338)

Do you mind inspecting the missing icon element and provide the findings? That could help to provide additional information about the issue.

Sure:

It seems to incorrectly add the full url after the path prefix (which is probably added via tomcat/servlet context path?)

Yeah, that would be part of the issue I linked before.
This issue targets the typo in the icon registry which was "icon-bitbucket-scmnavigator icon-<size>" instead of "icon-bitbucket-scm-navigator icon-<size>" before, that caused the default icon to not show.

Between JENKINS-67823, JENKINS-67849, JENKINS-67869, and JENKINS-67877 I am having a hard time understanding what issues remain at the time of current writing. If you are still experiencing an issue and are running the latest weekly and latest plugins, please leave a comment in JENKINS-67823 (not this ticket!) so that we can assess what remains to be done for this work unit.
