希望有人可以指出在使用Hudson进行Maven构建时可能导致致命错误的问题。
我刚刚在测试环境中的Windows XP盒子上安装了Tomcat中的Hudson实例。我是哈德森的新手。我试图在一个小型Java项目上做一个简单的Maven“clean”，我知道在另一台服务器上另一个Hudson实例上构建得很好。
Hudson控制台的堆栈跟踪如下：
谢谢

答案 0 :(得分：1)
您是否碰巧将您之前的哈德森计算机上的作业（或整个哈德逊根目录）复制并粘贴到您安装的目录中？ classnotfound异常是hudson / xstream试图解组构建配置的产物。
发生这种情况的一个原因是因为您在一台机器上使用版本构建了hudson，然后尝试将构建配置复制并粘贴到本地实例并使用不同版本运行hudson。
我的建议是，如果情况是同步本地计算机以获得先前运行的相同版本的哈德森。
答案 1 :(得分：0)
我没有升级或使用任何其他版本的hudson或复制任何任务。我也收到了这个错误！检查Hudson我看到1.395版本可用。然而，我确实安装了M2 maven发布插件....似乎它的东西1.394？我没有改变我的工作来使用它，但它失败了。
