ClassNotFoundException

I'm trying to make my first bukkit plugin, and I just get this error.

Code:

18:58:51 [SEVERE] Could not load 'plugins\TestPlugin.jar' in folder 'plugins':

I have searched this problem, and its suppose to be fixed by adding the class name at the end.. I have.

This is my code:

Code:

package me.russjr08.plugins;
 
import java.util.logging.Logger;
 
import org.bukkit.plugin.java.JavaPlugin;
 
public class TestPlugin extends JavaPlugin {
 
    Logger log = Logger.getLogger("Minecraft");
   
    public void onEnable(){
       
        log.info("TestPlugin has successfully been enabled!");
   
    }
   
    public void onDisable(){
       
        log.info("TestPlugin has sucessfully been disabled!");
       
    }
}

And my plugin.yml is

name: TestPlugin
main: me.russjr08.plugins.TestPlugin
version: 1alpha1
description: >
A test plugin.

 

In your plugin.yml file
make sure its

Code:

main: me.russjr08.plugins.TestPlugin.TestPlugin

 

Unfortunately with that I get basically the same error:

Code:

19:39:08 [SEVERE] Could not load 'plugins\TestPlugin.jar' in folder 'plugins':

Try opening the Jar file and make sure the class file is in there. And go back to your original main class, it was correct before.

 

O.O Only the plugin.yml is in there and META-INF

Ok, reverted the plugin.yml and fixed it. Apparently I didn't use Export correctly. Right click the project Folder and click Export, not from The File menu.

Thanks everyone!

 

Thanks for helping me man! i didnt know i was exporting it wrong!
