只是想知道是什么导致了这种情况。我不知道！
我正在尝试制作一个队列插件。我用的是纸龙头。请忽略我插件代码中的所有漏洞，因为我现在只是在测试它。如果你有什么你认为我应该改变的，但我很乐意在这里。这是我的错误信息吐出来的终端。

else

}
最后是我的plugin.yml(如果这是错误的(
main: com.Package.AnarchyQueue
name: AnarchyQueue
version: '1.0'
description: The queue plugin for Ed_Silver's anarchy server.
load: postworld
author: Ed_Silver
prefix: AnarchyQueue
commands:
setmaxplayercount:
description: Sets max player count
usage: /setmaxplayercount [int]
我看到一篇关于需要使用pom.xml添加依赖项的帖子，但我不知道这是否适用于我
提前感谢
如果你需要什么，只要问一下，

您正在尝试import redis.clients.jedis.Jedis;，但Minecraft找不到Jedis，您必须将Jedis添加到您的maven或gradle项目中。
根据https://github.com/xetorthio/jedis：https://github.com/xetorthio/jedis#how-do-i-use-it
希望这能有所帮助，我在这里回答您的任何问题！
