任务'：app：transformClassesAndResourcesWithProguardForRelease'的执行失败：java.io.IOException - Proguard问题

尝试使用proguard时，一直在努力找出问题背后的原因（请参阅下面的stacktrace）。任务'：app：transformClassesAndResourcesWithProguardForRelease'的执行失败：java.io.IOException - Proguard问题

从gradle这个文件中提到的库

除此之外，与开放sockets，serializing/deserializing数据，ciphers和jwt tokens，处理WifiManager & WifiP2pManager应用程序交易。

如果有人能够帮助指出问题，或者至少帮助我更好地解决问题，那将是非常棒的。我试图为不同的库添加所有可能的proguard规则，并且不要缩小我们自己的父包。

我gradle这个文件
