我正在开发一个不和谐机器人，但是我遇到了一些我从未遇到过的问题。我的discord机器人无法发送消息。bot不包含任何不推荐使用的方法。代码如下：
主要内容：

private Main() throws LoginException {
    final JDA jda = JDABuilder.createDefault("My.Token.Here", GatewayIntent.GUILD_MEMBERS, GatewayIntent.GUILD_EMOJIS, GatewayIntent.GUILD_VOICE_STATES).build();

    CommandClientBuilder builder = new CommandClientBuilder();
    builder.setOwnerId("778564522046128148");
    builder.setActivity(Activity.watching("es bueda fixe!"));

    CommandClient client = builder.build();

    jda.addEventListener(client);
    jda.addEventListener(new JoinLeave());
    jda.addEventListener(new TestCommand());
}

public static void main(String[] args) throws LoginException{
    long enable = System.currentTimeMillis();
    new Main();
    System.out.println("Bot enabled in: " + (System.currentTimeMillis() - enable) + "ms!");
}

testcommand（测试bot是否工作）：

public class TestCommand extends ListenerAdapter {

@Override
public void onGuildMessageReceived(GuildMessageReceivedEvent e){
    System.out.println("hefdfs");
    if(e.getMessage().getContentRaw().equalsIgnoreCase("!test")){
        e.getChannel().sendMessage("test").queue();
    }
}

}
谢谢。
