Solved Can't load my plugin

I'm making a plugin.
When I'm starting my server, there is an error

Code:

[14:22:36] [Server thread/ERROR]: Could not load 'plugins\WarnCommands_1.12.jar' in folder 'plugins'

plugin.yml:

Code:

name: WarnCommands
main: com.warncommands.Main
version: Alpha 1.0
author: Arbuzik999
description: WarnCommands

commands:
    warn:
        description: Info about WarnCommands.
        permissions: warncommands.warn
        usage: /<command>
      
permissions:
    com.warncommands.warn:
        description: Allows to /warn.

 

@timtower
it is exporting

 

The same thing..

 

This error is when I trying to add a command. When I'm removing command from plugin.yml, it is working.

It doesn't work. Tried to replace it manually. Even set the option in Notepad++

Also Eclipse sends me this error, but when I reclicking the "Finish" button, there is no error.

 

Oh, forgot for image

 

Doesn't helps..

Maybe it is code error?

Code:

package com.warncommands;

import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

import net.md_5.bungee.api.ChatColor;

public class Commands implements CommandExecutor {
  

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
      
            if (sender instanceof Player)
            {
                if (cmd.getName().equalsIgnoreCase("warn"))
                {
                    Player player = (Player) sender;
                    player.sendMessage(ChatColor.YELLOW + "WarnCommands\n\n" + ChatColor.GREEN + "Author: Arbuzik" + ChatColor.RED + "999\n" + ChatColor.GREEN + "Version: " + ChatColor.YELLOW + "Alpha 1.0" );
                    return true;
                }
            }
            return false;
    }

}

Main class:

Code:

package com.warncommands;

import org.bukkit.event.Listener;
import org.bukkit.plugin.java.JavaPlugin;

import net.md_5.bungee.api.ChatColor;

public class Main extends JavaPlugin implements Listener {
   
    public Commands commands = new Commands();
   

    public void onEnable() {
        getCommand("warn").setExecutor(commands);
        getServer().getConsoleSender().sendMessage(ChatColor.RED + "Warn" + ChatColor.GREEN + "Commands"  + ChatColor.AQUA + " has been successfully enabled!");
    }
   
    public void onDisable() {
        getServer().getConsoleSender().sendMessage(ChatColor.RED + "Warn" + ChatColor.GREEN + "Commands"  + ChatColor.AQUA + " has been successfully " + ChatColor.RED +  "disabled!");
    }
   
}

yes

 

same.

 

What's all the confusion about, just move the plugin.yml to the src folder?

Also if your problem is solved, please mark the thread as solved!

 

Solved!! I renamed Main class to lower case and it works! Thanks everyone who tried to fix my error!

 

That's a bad solution. I think the problem is in your plugin.yml, try switching

Code:

main: com.whatever.myplugin.main

to

Code:

main: com.whatever.myplugin.Main

instead. "main: " points to your Main class, not just your package.

 

No, in plugin.yml it was uppercase.
