背景
项目中打包经常遇到混淆导致的各种bug（崩溃、闪退、无厘头），提醒过开发数次，问题还是时而发生。这时，人是不可靠的，错误时而发生，所以做了这么个脚本，旨在抛砖引玉。
思路
目的在于扫描项目，判断是否有实体被混淆。
说明：我们项目中出现最多的问题就是实体被混淆，所以这个脚本只是扫描实体的混淆情况。不排除其他混淆导致的问题，这里只是抛砖引玉，希望通过这个思路，让有被混淆困扰的童鞋能够做好这一块。
- 传入项目路径，扫描出所有路径
- 符合实体类的路径存入列表
- 与混淆配置文件对比
- 打印被混淆的实体类
实例
检测通过：
Checked pass.Time: 0.01 s
检测不通过（有实体被混淆）：
Errors, has some entities be garble.com.s.toutiao.entityTime: 0.01 s
实体被混淆导致的闪退：
FATAL EXCEPTION: main
Process: com.s.d, PID: 30138
java.lang.NullPointerException: Attempt to invoke interface method 'java.lang.String java.lang.CharSequence.toString()' on a null object reference

实体为什么不能混淆？
当然不能混淆了，实体混淆后就变成abc之流了，与接口返回的字段就对应不上，肯定会有问题。
