Solved 'Cannot find mainclass'

When trying to load up this plugin, I get this awfully weird error. I've tried solving this problem several times, with no luck. Hopefully somebody can help me! Thanks.


Main class:

Code:

package me.bukkit.floofybear;

import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;

import net.md_5.bungee.api.ChatColor;

public class Fluffybear extends JavaPlugin {
   
    public void onEnable() {
       
    }
       
       
        public void onDisable() {
       
       
    }
       
        public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
            if(cmd.getName().equalsIgnoreCase("hello")) {
               
                Player player = (Player) sender;
               
                player.sendMessage(ChatColor.RED + "Welcome, my friend");
               
               
            }
           
           
            return false;
           
           
           
        }
    
   

}

Plugin.yml

Code:

name: FluffyBear Test Server #1
main: me.bukkit.floofybear.Fluffybear
version: 1.0
commands:
   hello:
      description: Blank description.
      usage: /<command>

Error ( in console ):

Yes, I am new to this bukkit forums :/ If I did anything wrong, let me know and I'll correct it!

 

Please read this. No one should use 1.8 anymore. Update to 1.11.

It seems Java cannot find that class. Are you sure you are including this class when you export the project?

 

Thanks for the help. I managed to fix this issue Also, if I update to 1.11 can I still run a server on 1.8? It's probably a stupid question.

 

@FluffyBearr
Well, you can add features from 1.8 to 1.11 (such as the pvp system), but you cannot actually have 1.8 run on a 1.11 server (how would that work?).
