What's wrong with my plugin? :(

Hello Bukkit Community! So today I finished coding my plugin called "AstroNetwork" and exported it and all and uploaded it to my test server. But when I did /pl it didn't show up and none of the commands worked. Can someone tell me what went wrong? Thanks.

Main:

Code:

package com.astronetwork.effects;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.potion.PotionEffect;
import org.bukkit.potion.PotionEffectType;
public class Effects extends JavaPlugin {
  

  
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
        Player p = (Player) sender;
        if (cmd.getName().equalsIgnoreCase("speed")) {
            if (!p.hasPermission("astroeffects.speed")) {
                p.sendMessage(ChatColor.RED + "You do not have permission!");
            } else {
                p.addPotionEffect(new PotionEffect(PotionEffectType.SPEED, 3000, 1));
                p.sendMessage(ChatColor.GREEN + "You have received SPEED for 5 minutes!");
                return true;
        }
        }
            if (cmd.getName().equalsIgnoreCase("strength")) {
                if (!p.hasPermission("astroeffects.strength")) {
                    p.sendMessage(ChatColor.RED + "You do not have permission!");
                } else {
                    p.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 3000, 1));
                    p.sendMessage(ChatColor.GREEN + "You have received STRENGTH for 5 minutes!");
                    return true;
                }
            }
            if (cmd.getName().equalsIgnoreCase("invis")) {
                if (!p.hasPermission("astroeffects.invis")) {
                p.sendMessage(ChatColor.RED + "You do not have permission!");  
                } else {
                    p.addPotionEffect(new PotionEffect(PotionEffectType.INVISIBILITY, 3000, 1));
                    p.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 3000, 1));
                    p.sendMessage(ChatColor.GREEN + "You have received INVISIBILITY for 5 minutes!");
                    return true;
                }
            }
            return true;
    }
      
  
}

Plugin.yml:

Code:

name: AstroEffects
version: 1.1
main: com.astronetwork.effects.Effects
authors: [JustNiico, Lexuss]
commands:
    speed:
        description: Get speed for 5 minutes.
    strength:
        description: Get strength for 5 minutes.
    invis:
        description: Get invisibility for 5 minutes.

 

@Just_Niico Do not use unsafe casting. A CommandSender isn't always a Player. Please post full startup log.

 

@AdamQpzm shall I do instanceof Player?

 

@Just_Niico Yup

 

@AdamQpzm I'm not sure where to put it... do I put it after my onCommand?

 

@Just_Niico You'll want to place it in such a fashion that, should instanceof Player return false, you don't try to cast it to one. If you can't work out where or how you'd do that, then you probably need to learn more about Java

 

@Just_Niico Where is your onEnable() class?

 

@Just_Jitse The onEnable() is optional.

 

@Just_Jitse I don't have one

@AdamQpzm
So

if (sender instanceof Player) {
//code goes here
}

} else {
//code goes here for console
}
?

@AdamQpzm @Just_Niico
ow yeah ofcource, stupid -,-

 

@Just_Niico That could work, sure

            if (!p.hasPermission("astroeffects.speed")) {
                p.sendMessage(ChatColor.RED + "You do not have permission!");
            } else {
                p.addPotionEffect(new PotionEffect(PotionEffectType.SPEED, 3000, 1));
                p.sendMessage(ChatColor.GREEN + "You have received SPEED for 5 minutes!");
                return true;

                } else {
                    p.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 3000, 1));
                    p.sendMessage(ChatColor.GREEN + "You have received STRENGTH for 5 minutes!");
                    return true;
                }
            }
            if (cmd.getName().equalsIgnoreCase("invis")) {
                if (!p.hasPermission("astroeffects.invis")) {
                p.sendMessage(ChatColor.RED + "You do not have permission!"); 
                } else {
                    p.addPotionEffect(new PotionEffect(PotionEffectType.INVISIBILITY, 3000, 1));
                    p.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 3000, 1));
                    p.sendMessage(ChatColor.GREEN + "You have received INVISIBILITY for 5 minutes!");
                    return true;
                }
            }
            return true;
    }
    
}

I see the error but don't know what it means... I also have no errors in my Eclipse.

 

There's the answer.

 

Basically, what he's trying to say is you used tab in your plugin.yml. NEVER use the tab key in your plugin.yml. Use spaces instead

 

@SuperOriginal @2008Choco That's strange, I used spaces in my plugin.yml.

 

Show us your plugin.yml (use upload a file)
