执行freeline.py 时间跟全量一样，并且第二次执行就报错

使用的freeline版本0.8.4，gradle版本2.14.1，gradle tool版本2.1.3，python版本2.7
根据#152 验证，版本一致，没有用代理，使用-f全量编译后，随便修改一行代码，第一次执行python freeline.py 时间跟全量编译一样，再修改一行代码，执行 python freeline.py 就报上面的错误

@hluguoj 会出现这个情况大部分给 issue 152 提到的情况有关，代理也包括 Android Studio 本身开的代理...你也可以重启一下手机试试看，或者换一下手机，多测试看看

@lomanyong 这个问题已经解决了，应该是我这边的productFlavor填写的问题，我用了已有的productFlavor，但是我们对打包流程进行了改造，插入了很多自定义的task。我新创建了一个productFlavor，使用新创建的productFlavor就没有问题了。谢谢你
