呈现宏时出错 - 无法初始化 class org.apache.xmlrpc.util.SAXParsers

Question

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

我测试了我的 Java xml-rpc 客户端在 eclipse 中终止它（主要功能） - 它完美运行，

但是当我尝试将它与 confluence 连接时，我得到 error:

（宏安装成功 - 输出错误）

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

有人可以帮助我了解这里发生了什么吗？我读到它可能是外部 jar 的问题 - 但给出的答案不能解决我的问题。

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

这是我到目前为止完成的代码：

    }

       public static String testLinkReport(String link)
       {

        String tcid = link.substring(link.lastIndexOf("=")+1);
           try
           {
               XmlRpcClient rpcClient;
               XmlRpcClientConfigImpl config;

               config = new XmlRpcClientConfigImpl();
               config.setServerURL(new URL(SERVER_URL));
               rpcClient = new XmlRpcClient();
               rpcClient.setConfig(config);       

               ArrayList<Object> params = new ArrayList<Object>();
               Hashtable<String, Object> executionData = new Hashtable<String, Object>();   

               executionData.put("devKey", DEV_KEY);
               executionData.put("testcaseexternalid", tcid);
               params.add(executionData);
               Object[] result = (Object[]) rpcClient.execute("tl.getTestCase", params);

                   Map item = (Map)result[0];
                   title = tcid+":"+ item.get("name").toString();


           }

               e.printStackTrace();
           }
           return title;
       }

问题已解决。

已将 'exclude' 添加到 here

等依赖项

然后我不得不从 .jar 文件中删除 SAXParsers class，现在可以了:)

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.
