From the branch indexing logs, it is not always obvious when a branch meet or doesn't meet the defined criteria.

In one of my experiments, I just forgot to add the marker file (.cloudbees.md) to the repository, and so the branch indexing kept saying did not met criteria without any additional clue.

I think it should be more explicit like :

• missing .cloudbees.md marker file
• matched exclusion rule "forbidden"
• didn't match inclusion rule "allowed"
