      I upgraded to the latest git plugin (as part of upgrading all plugins), 3.6.2, and the multibranch pipeline builds all started to show no branches. I checked the index log and it seems that the index can no longer access the git repo:

      If I downgrade to 3.6.0 the pipeline index scan can correctly scan the repo
