Du musst sicherstellen dass alle erforderlichen Bibliotheken und Abhängigkeiten für deinen Discord-Bot vorhanden sind und korrekt eingebunden wurden. Die JDA-Bibliothek (in diesem Fall "net.dv8tion.jda.api.JDABuilder") muss in deinem Klassenpfad (Classpath) enthalten sein.

    public static void main(String [] args){
        String to = "z";//change accordingly
        String from = "y"; //change accordingly
        String host = "x";//or IP address

        //Get the session object
        Properties properties = System.getProperties();
        properties.setProperty("mail.smtp.host", host);
        Session session = Session.getDefaultInstance(properties);

        //compose the message
        try{
