Couchbase DCP 客户端 0.10.0 失败 java.lang.NoSuchMethodError

Question

我正在开发具有以下版本的 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 版本 1.2.7（这是自动的拉)

每当我运行我的应用程序时，我都会遇到以下异常。我尝试更改这些库的版本，但还没有成功。如果有人能提供帮助，我们将不胜感激。

Answer 1

一行解决：使用dcp-client版本0.10.0和core-io版本1.4.4，这个问题就会消失。

我从 Couchbase 的朋友那里得到了答案；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。

class NodeInfo 已在最新版本 core-io (v1.4.6) 中更改；方法 NodeInfo.hostName() returns 一个新的 class 称为 NetworkAddress。在以前的版本中，它返回 InetAddress。出于某种原因，Couchbase 人员没有更新 dcp-client 版本 0.10.0 以使用较新的 API。根据上面 link 中的讨论，他们将很快发布。
