[JENKINS-73577] Subversion include branches are scanned too many times #1574
Description
All included branches are being scanned for a Jenkinsfile for each included pattern. In production, the same branch is being scanned 32 times, resulting in an execution time of 30 seconds for the multibranch scan, rather than 1 second. We have 16 included patterns.
Project repository base: svn://repo/repo1
Include branches: branches/TeamA-, branches/BUG-
Example output (a test repo with only a couple of branches):
