Plugin Not Executing Commands

Hello!
As the title says, my plugin is showing up in /pl but none of my commands are working! It just says "Unknown command."

Here's my Main.java, which is where I believe the issue lies in

Code:

package me.DrawThatRedstone.chatutils;

import java.util.ArrayList;
import java.util.List;

import org.bukkit.Bukkit;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin{
 
    public static List<String> muted = new ArrayList<String>();
    @Override
    public void onEnable() {
        getCommand("clearchat").setExecutor(new ChatClear());
        getCommand("mutechat").setExecutor(new ChatMute());
        Bukkit.getPluginManager().registerEvents(new ChatListener(), this);
    }

}

and here's the error that's coming into my console

Code:

[23:02:26 INFO]: [ChatUtils] Loading ChatUtils v0.1
[23:02:26 INFO]: [ChatUtils] Enabling ChatUtils v0.1
[23:02:26 ERROR]: Error occurred while enabling ChatUtils v0.1 (Is it up to date?)

Thank you!

And in your plugin.yml ?
Do you have :

Code:

commands:
  clearchat:
    description: Clear the chat
  otherCommand:
    description: other

 

@DrawThatRedstone
Are you sure you registered "clearshat" and "mutechat" in the plugin.yml?
