Commands not showing up.

I've been trying to get a custom command plugin functioning for my 1.21 server. For some reason, even thought the .yml and class files should be formatted correctly, the commands are not registering in the actual game. I'm pasting the two class files and the yml file below. If anyone could help me out, i would be thankful.

Main Class

@Is3kai I can't recall whether command registration is necessary in the main class, but just in case, try that. Additionally, if you have any errors in your server log, please post them here as well using pastebin or similar.

 

That's the odd thing, there are no errors in the server log.

The plugin is functioning, but the commands aren't registering. The PvP Death Ban is working, but nothing else. And if the kick without invite is uncommented, it also functions.

 

@Is3kai I tried compiling the source code you provided and run it on a Spigot 1.21 server (to be exact: CraftBukkit version 4258-Spigot-491f367-8fd64b0 (MC: 1.21) (Implementing API version 1.21-R0.1-SNAPSHOT)).
I could not reproduce the problem; the commands registered just fine for me. What server software do you use? I notice you mentioned "paper.yml" rather than "plugin.yml".

 

I'm trying to run it on a paper server, but none of the commands are registering or showing up when I run the /help command.
I said paper.yml cause the file is a paper-plugin.yml file
