Simple problem, help needed

Ive recently re-started my plugin development hobby. I decided to get a little refreshed with some methods and simple code.
I wrote some code but it seems everytime I put it into a my own local server the plugin shows up (when i do /pl) but the command just doesnt seem to want to show up)

Main class code

Code:

package com.Andrew;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
public class UltDestruction extends JavaPlugin{
 public void onEnable(){
  
 }
 public void onDisable(){
  
 }
 public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
     if(cmd.getName().equalsIgnoreCase("ignite")){
         Player s = (Player)sender;
         Player target = s.getServer().getPlayer(args[0]); 
         target.setFireTicks(10000);
         return true;
     }
     return false;
 }
}

Yml file:

Code:

name: UltDestruction
 
main: com.Andrew.UltDestruction
 
version: 0.0.1
 
commands:
 
basic:
 
description: This is a demo command.
 
usage: /<command> [player]
 
permission: UltDestruction.ignite
 
permission-message: You don't have <permission>
 

 

If you register the command "basic" you can't use the command "ignite".
You have to register ignite in the plugin.yml

 

in plugin.yml change "basic" to "ignite"

 

I changed it yet it still gives me the unknown command error

[Edit] nevermind, it seems the plugin.yml was in a bad format. Thanks anyway <3
