我正在尝试使用java discord api构建discord bot，但在运行以下代码段时：

public static void main(String[] args) throws LoginException {
    JDABuilder builder = JDABuilder.createDefault(token);
    builder.setActivity(Activity.watching("boop"));
    builder.build();
}

它引发以下异常：

Exception in thread "main" java.lang.NoClassDefFoundError: gnu/trove/map/TLongObjectMap
at net.dv8tion.jda@4.2.0_216/net.dv8tion.jda.api.entities.Activity.watching(Activity.java:204)

为什么要扔这个，我该怎么修？
