为什么我的java程序抛出java.lang. nosuchmethoderror使用JDA在heroku?

Question

我在Heroku上托管了这个java discord bot，在升级到最新版本的JDA后，我不得不将onGuildMessageReceived更改为onMessageReceived。当从intelllij运行我的bot时，它没有任何问题，但当从Heroku执行它时，它会给我"java.lang。NoSuchMethodError:"net.dv8tion.jda.api.entities。音频信道net.dv8tion.jda.api.entities.GuildVoiceState.getChannel()";每次我在Discord上发消息。导致此错误的代码为:AudioChannel audioChannel = e.getMember().getVoiceState().getChannel();inside ofonMessageReceived.

我个人觉得maven可能导入了错误的版本到Heroku，但我没有任何方法来检查它，所以这里是我的pom.xml:

根据我的经验，java.lang.NoSuchMethodError通常意味着存在jar冲突，这表明有多个jar文件包含某个class。你可以简单地双击shift并搜索特定的类名来检查是否有多个jar包含特定的类
