Question

我正在尝试运行JDA Discord Bot，但出现此错误：

[JDA MainWS-ReadThread] INFO net.dv8tion.jda.core.requests.WebSocketClient - Connected to WebSocket
[JDA MainWS-ReadThread] ERROR net.dv8tion.jda.core.requests.WebSocketClient - There was an error in the WebSocket connection
java.lang.NoSuchMethodError: org.json.JSONArray.iterator()Ljava/util/Iterator;

    at com.neovisionaries.ws.client.WebSocketThread.run(WebSocketThread.java:45)

我找不到问题所在

这是我的pom.xml：https://hasteb.in/agaseniz.xml
我的引用库中也有这些库：http://prntscr.com/nfdquv

我曾在JDA GitHub上问过，但他们说我必须获取已经拥有的最新org.json。所以我很困惑。

希望有人可以在那里帮助我。

Answer 1

实际上，org.json.JSONArray.iterator()从一开始就不存在，但是was added later。

您的pom.xml看起来不错，但是在引用库 中，有 json-simple-1.1.1.jar而不是json-20180813.jar 。

右键单击项目，然后选择 Maven>更新项目...
