Using loggers that aren't the plugin's (for example by using this.getLogger() in the main class) is frowned upon, since it causes a variety of little issues in some cases. Unless it's not required by some restriction or issue, you shouldn't use the Minecraft logger in the API classes.

this.getLogger() returns the plugin logger according to the API documentation. What issue are you seeing when using the plugin logger?

Yes, that's fine, but in some classes the "Minecraft" logger is used instead

@DoNotSpamPls okay, your initial comment was a bit confusing since it was calling out this.getLogger() as problematic.
