java - 渲染宏出错 - 无法初始化类 org.apache.xmlrpc.util.SAXParsers

Question

我正在创建 confluence 宏，它应该执行我的 Java xml-rpc 客户端。

我测试了我的 Java xml-rpc 客户端，在 eclipse 中终止它(主要功能)- 它工作完美，

但是当我尝试将其与 confluence 连接时，我收到错误:

(宏已成功安装 - 输出出现错误)

Error rendering macro 'TESTLINK PLUGIN' : Could not initialize class org.apache.xmlrpc.util.SAXParsers

有人可以帮我理解这里发生了什么吗？我读到这可能是外部 jar 的问题 - 但给出的答案并不能解决我的问题。

我还使用mvn-install命令安装了我的xmlrpc，并将依赖项添加到我的pom.xml中，SAXParsers应该包含在那里......

这是我到目前为止所做的代码:

问题已解决。

向依赖项添加了“排除”，例如 here

之后我必须从 .jar 文件中删除 SAXParsers 类，现在它可以工作了:)

The problem is that the Apache XML-RPC client library you are using has a multitude of other dependencies that it will bundle into your plugin when you compile, and they clash with libraries already shipped in JIRA.
