In the docs for scm-sync-configuration-plugin it states,

Following includes are brought "out of the box" by scm-sync-configuration default includes :

• config.xml
• hudson*.xml
• jenkins*.xml
• scm-sync-configuration.xml
• jobs/*/config.xml (* restricted to real project and folder directories)
• users/*/config.xml

Newer plugins, however, have their configuration stored under `org.jenkinsci.plugins.rundeck.RundeckNotifier.xml`, which is not covered by these defaults.

I've worked around the issue by adding `org.jenkinsci.*.xml` as a manual pattern but it would help others to have this added to the defaults.

Thanks,
