本文介绍了一种 Hudson 在进行 Maven 构建时突然失败的问题，并提供了一个临时解决方案，即通过修改特定 JSON 文件来修复。

查看异常堆栈貌似跟项目配置和代码没有任何关系，google搜貌似是hudson的bug。找了半天没找到官方解决办法。

于是采用比较旁门左道的解决方案：

http://blog.progs.be/133/hudson-builds-suddenly-fail-due-to-a-bug-in-the-code

" For some reason this is caused by the $HUDSON_HOME/updates/hudson.tasks.Maven.MavenInstaller file which was empty.

Putting “{}” (an empty JSON object) in there allowed builds to work again."

找HUDSON_HOME找了半天，后来全盘搜才找到，原来hudson启动是会自动建立 ".hudson"文件夹

tomcat中会有提示信息

INFO: Home directory: /root/.hudson

在里面能找到一个文件 hudson.tasks.Maven.MavenInstaller

vi 编辑，添加{}

重新运行hudson，问题暂时解决了。
