I noticed this issue after merging a git submodule into a parent repository. e.g., previously the repo had a submodule with name "libA" and now there is a directory with name "libA" which has identical contents to the submodule.
A jenkins job used to point at a Jenkinsfile in the submodule root, and I reconfigured it to point to the parent repository with path "libA/Jenkinsfile".
The branch indexing succeeds for branches where the submodule was merged, but hard fails if it scans a branch where the submodule is still present.
I don't expect Jenkins to recursively scan into the submodule, but I think it should return SCMFile.Type.NONEXISTENT and skip the branch as though the file was not found. Hard failing and cancelling the rest of the branch indexing task seems like a bug.
I can't easily identify where to contribute this myself, otherwise I would.
