Question

我正在使用以下版本的DCP客户端连接器。

DCP客户端版本0.10.0
Java客户端版本2.4.6
核心IO版本1.4.6
Rx Java版1.2.7（这是自动的拉动）

每当我运行我的应用程序时，我都会遇到异常。我尝试改变这些库的版本，但还没有运气。感谢有人可以提供帮助。

一行中的解决方案：将dcp-client版本0.10.0与core-io版本1.4.4一起使用，此问题就会消失。

我从Couchbase人那里得到了答案;整个讨论都在这里https://forums.couchbase.com/t/couchbase-dcp-client-0-10-0-fails-with-java-lang-nosuchmethoderror/13227。

最新版NodeInfo（v core-io）中的班级1.4.6已更改;方法NodeInfo.hostName()返回一个名为NetworkAddress的新类。在以前的版本中，它返回InetAddress。由于某些原因，Couchbase人员未更新dcp-client版本0.10.0以使用较新的API。根据上述链接中的讨论，他们很快就会发布。

Couchbase DCP Client 0.10.0因java.lang.NoSuchMethodError而失败
