We use Polling Ignores Commits in Certain Paths option to poll for changes in a specific directory of the git repo. It works smooth until we merge changes from another branch onto the polled branch.

Even though the merged changes don't come under the Included Regions, builds get triggered.

Job Config looking for changes only under "harsha" directory.

Build triggered by changes polled under a different directory

Ideally even when the merge happens, the plugin should trigger changes based on the included regions.
