When using the GitHub plugin, if your project mixes both GitHub and non-GitHub repos (e.g. your project source is in GitHub but your Pipeline shared libraries are in Bitbucket), your Jenkins logs are polluted with endless warnings:

WARNING c.c.jenkins.GitHubRepositoryName#create: Could not match URL ...

I have seen this warning hundreds of times in the span of a few minutes on a busy master. Perhaps it would be worth simply logging this at DEBUG level rather than WARNING. Otherwise, I would propose adding a global config option where a user can list non-GitHub repos that are used in their environments, and the plugin will ignore these.
