Environment:Jenkins 2.19.3 LTS, pipeline multibranch plugin 2.9.2
The attached Jenkinsfile performs an additional checkout step from "some other" location than the Jenkinsfile repo.
When used in a multibranch pipeline, changes to the "other" repo are not detected by the branch indexer. A normal pipeline job using the same Jenkinsfile will correctly poll for changes to this other repo.
Test Repo Structure
- root-folder
|- branches
|- branch-a
|- foo.txt
|- Jenkinsfile
|- branch-b
|- bar.txt
|- Jenkinsfile (same as branch-a)
|- other-lib
|- baz.txt
Pipeline Job (correct polling)
- Poll SCM: Enabled (H/10 * * * *)
- Pipeline script from SCM: https://url/to/branches/branch-a
- Local Module Directory: empty
1. Build once, observe checkout from branch-a and other-lib as per Jenkinsfile
2. Modify other-lib/baz.txt in SCM
3. Observe polling log detect changes to other-lib:

Multibranch Pipeline Job (branch indexing)
- Project Base: https://url/to/branches
- Include Branches: *
- Periodically if not otherwise run: 1 minute
1. Initial branch indexing detects both branches and generates subjobs / schedules them
2. Modify other-lib/baz.txt in SCM
3. Observe indexing log does not detect this change

Expected Result
For the behaviour to be consistent between these two job types - the branch indexer should be able to detect these changes considering comment on JENKINS-34737 stating this polling behaviour is subsumed into the indexing.
