Solved Its keeps saying its not seeing Main

When I try to use my plugin it gives an error in console but I can't see to fix it.

Code:

Code:

package com.nodupechat.plugin;

import java.util.HashMap;

import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.AsyncPlayerChatEvent;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin implements Listener {
  
    @Override
    public void onEnable() {
        org.bukkit.Bukkit.getPluginManager().registerEvents(this, this);
    }
  
    HashMap<String, Boolean> Chat = new HashMap<String, Boolean>();
    @EventHandler
    public void onChat(AsyncPlayerChatEvent e) {
        String Message = e.getMessage();
        if(Message == Chat.getOrDefault(Message, true)) {
            Player player = e.getPlayer();
            player.sendMessage(ChatColor.GOLD + "You cannot say the same message twice");
        }
        Chat.put(Message, true);
    }
}

Console:

This is what it looks like but I am not sure if I might of unchecked or checked anything by accident, does it look alright? also, I have implemented the spigot.jar and the JavaDoc so I'm not sure about that (also I know your plugin is called "NoDupeChat" but mine was called different, I just changed it to that because it gave me errors and I wondered if it was my name for it)

When i export the jar file i look into what it is actually exporting and it has the src files checked, everything should be working

Update: I had to tick "Export Java source files and resources", but it was never ticked and still worked
Update 2: It gives the source file and the rest but still gives error in console:

Any ideas @timtower

WinRAR of plugin:

 

Yes @timtower

 

I don't know why it keeps making into a java file and not a class, i am just going to reinstall ecplise and see if my settings reset to default

 

@timtower ok, I can't even unistall ecplise anyway xD
This is what it looks like:

Apparently when I check "Export java files and resources", it exports the package and java file but I never use to have to do this.
Also, this popped up:

 

K @timtower but how did you know there was a bin folder from that error?

 

Cool @timtower, i test it when i get home, im omw now

@timtower I deleted the bin file and it still does not work.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.
EDIT by Sender: Sorry I am not sure if @s work when you edit posts

 

@timtower same error and this is what they look like:

and:

 

@timtower 1 is package explorer and the other is a navigator, what do you mean by normal non-ecplise file explorer?

 

i have no clue what that is sorry

 

@timtower are you just talking about windows folders?

 

@timtower

 

@timtower seem to export everything well, I think I might have just had to delete src file and recreate it then add the Main.java to it
