【转载】解决CheckStyle builder的Error

最近需要调整项目代码，所以安装了一个CheckStyle的Eclipse插件。但在workspace里面的项目自动开始build的时候，碰到如下问题：

Errors occurred during the build.
Errors running builder 'Checkstyle Builder' on project [projectname].
Fileset from project [projectname] has no valid check configuration.
Fileset from project [projectname] has no valid check configuration.
Fileset from project [projectname] has no valid check configuration.
Fileset from project [projectname] has no valid check configuration.

然后搜了搜，发现一篇博客，其中的方法确实可以搞定上述问题，故此留存，以备后用：
