How can I fix this JDA discord bot error?

Question

I have one problem with JDA, when I try to load an event to detect new messages on a Discord channel, it doesn't detect it, but it detects private messages, I don't know how I can fix this.

public static void main(String[] args) {
    try {
        JDA jda = new JDABuilder(AccountType.BOT).setToken("---").build();
        System.out.println("asd");
        jda.addEventListener(new Core());
    } catch (LoginException e) {
        e.printStackTrace();
    }


}

 // this workds and detecting private messages
@Override
public void onMessageReceived(MessageReceivedEvent event) {

    if(event.getAuthor().isBot()) {
        return;
    }

    System.out.println("asdasdasds");

}

        //no detect public channel messages
@Override
public void onGuildMessageReceived(GuildMessageReceivedEvent event) {

    if(event.getAuthor().isBot()) {
        return;
    }

    System.out.println("bsbsbsbsb");

}

You're using a deprecated constructor for JDA.

You should use JDABuilder#createDefault() or one of the other non-deprecated ways to construct JDA.
