【问题描述】：
我正在尝试为 cassandra 制作 Intellij 插件。在构建了 intellij 社区源代码之后，我设法进入了开发部分。我已经通过 maven (com.datastax.cassandra:cassandra-driver-core:3.0.0) 添加了 cassandra 驱动程序。但是当我部署插件时，它给了我链接错误（slf4j 记录器）。所以我将它从 cassandra 驱动程序库中排除。之后我在连接到 cassandra 时遇到了这个异常
ClassCastException: io.netty.channel.epoll.EpollEventLoopGroup cannot be cast to io.netty.channel.EventLoopGroup
这里是堆栈跟踪：

如何摆脱这个异常？我曾尝试降级 cassandra 驱动程序版本，但没有成功。
【问题讨论】：
-
你有没有机会开源这个插件？我正在尝试做同样的事情，但找不到任何关于从哪里开始的信息
-
这个插件能走多远？我想用它..
