Help With Plugin.yml File

I am writing a double jump plugin.
My Code:

Code:

package me._EnderWizard_.DoubleJump;
import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.EntityDamageEvent;
import org.bukkit.event.entity.EntityDamageEvent.DamageCause;
import org.bukkit.event.player.PlayerMoveEvent;
import org.bukkit.plugin.java.JavaPlugin;
public class Main extends JavaPlugin implements Listener{
    @Override
    public void onEnable() {
        this.getServer().getPluginManager().registerEvents(this, this);
    }
    @Override
    public void onDisable() {
    }
    @EventHandler
    public void onJump(PlayerMoveEvent event) {
        Player player = (Player) event.getPlayer();
        if(event.getFrom().getY() < event.getTo().getY() &&
                player.getLocation().subtract(0, 1, 0).getBlock().getType() == Material.AIR) {
            player.setVelocity(player.getLocation().getDirection().multiply(2).setY(2));
        }
    }
  
    @EventHandler
    public void onFall(EntityDamageEvent event) {
        if(event.getEntity() instanceof Player) {
            Player player = (Player) event.getEntity();
            if(event.getCause() == DamageCause.FALL) {
                event.setCancelled(true);
            }
        }
          
    }
      
}

My plugin.yml:

Code:

main: me._EnderWizard_.DoubleJump.Main
name: DoubleJump
version: 1.0.0
author: _EnderWizard_

The console is saying that there is an error in my plugin.yml, but I don't see it. Help?
I know that there are probably some bugs in my code, but none that should affect the plugin's ability to run. Any help is appreciated.

 

Thank you so much for replying.

@_EnderWizard_ Where is your plugin.yml? Can you show an image of your project tree?

 

I have added an image with the tree. Let me know if you need anything else.

 

Hm. Try moving your plugin.yml out of the package it's in and put it in the "src" folder.

 

I see what I did wrong, I put the yml in the package instead of outside. Thank you @KarimAKL and @timtower and @psuedo_su!
