Jenkins pipelines and SVN poll exclusions?

[Chris George]

We are using a jenkins pipeline, and for the life of me (much googling and reading) I cannot get the SCM Poll to ignore a certain directory in our SVN repo.

I'm adding the exclusion in the Pipeline -> Configure -> Pipeline -> Pipeline script from SCM ->  SCM section, but the polling doesn't take a blind bit of notice.

There are two questions I guess.

1. I'm assuming the Poll SCM functionality takes it settings from the "Pipeline script from SCM -> SCM" section?  If not, how does it work?

2. If 1 is true, then has anyone been able to exclude a directory or file from the polling?

Thanks in advance
