eclipse错误信息：

The project was not built due to "A resource exists with a different case: '/xxx/bin/classes/com/example/xxx'.". Fix the problem, then try refreshing this project and building it since it may be inconsistent xxx  (xxx为项目名称)。

报错原因：

包名与项目清单不一致（包括大小写），一般新建项目的项目清单和包名如下，

但是当我们将其他人的项目拉过来的时候由于包名等的不一致，需要修改项目清单的包名时，粗心的改成了和项目名一样的有大写的包名，导致报错。
