Question

我有一个版本为 3.4.10 的 zookeeper 和版本为 2.12.0 的 curator，但版本低于 3.5.8 的 zookeeper 对 log4j1 有严格的传递依赖。我想使用 log4j2 这就是为什么需要更新 zookeeper 版本。我尝试了不同的组合：

zookeeper 3.6.1 和 curator 5.1.0
zookeeper 3.5.9 和 curator 5.1.0
zookeeper 3.5.9 和 curator 5.0.0
zookeeper 3.5.9 和 curator 5.1.0 + 从 curator 中排除 zookeeper 依赖
zookeeper 3.5.9 和 curator 4.3.0 + 从 curator 中排除 zookeeper 依赖
zookeeper 3.6.1 和 curator 5.1.0 + 从 curator 中排除 zookeeper 依赖

所有这些选项都失败了。 1 个选项失败并显示以下堆栈跟踪：

 java.lang.NoSuchMethodError: org.apache.zookeeper.ZooKeeper.close(I)Z

2-6 个选项看起来具有相同的轨迹：

    at java.net.URLClassLoader.findClass(URLClassLoader.java:382)

实际上，ZooKeeperAdmin 类从 3.5.7 开始就出现在 Zookeeper 中，这就是为什么找不到它的原因。

有人可以提出任何建议吗？这是依赖版本的问题吗（我找不到 zk > 3.4 with curator 的任何详细信息）？或者有什么方法可以调试和了解这个问题？
