Start Problems (ClassNotFoundException)

[Beutilo]

Hey Guys
I have start problems with the API.
I already tried everything and I always get the same exception (ClassNotFoundException).

Hopefully you guys can help me.

package com.cekuy.Cekuy_Bot;

import net.dv8tion.jda.api.JDA;
import net.dv8tion.jda.api.JDABuilder;

public class hauptklasse {
	public static JDA jda;
	
	//main method
	 public static void main(String[] args) throws Exception 
	 {	
		 	//create JDA
		 	String token ="token";
		 	JDA builder = JDABuilder.createDefault(token).build();
		 	
	 }
	 
}

I forgot to use Maven or Gradle.
