because: Failure to verify dex file

E/System: java.io.IOException: Failed to open dex files from /data/user/0/cn.qssq666.pluginload/app_robot_out_dex/classes.dex because: Failure to verify dex file '/data/user/0/cn.qssq666.pluginload/app_robot_out_dex/classes.dex': Bad file size (1024, expected 940d)

其实还有其他错误，解决办法就是看看其他错误是啥，我这里提示重复的类。所以我的方法是排除那个dex不进行合并
