Subject: [PATCH] Use warning instead of direct throw

Dreeam's Note:
We use soft warning which in Paper is directly exception throw,
Only print warning to avoid break plugins directly.

Also see `Configurable LibraryLoader maven repos` patch,
able to match googleapi mirror urls, to replace to repo url we custom defined.
This able to switch back to maven central repo, to prevent
situation that dependencies exist in maven central, but not in mirror.
