【问题描述】：
我正在我的 Android 库项目上运行 Proguard 并处理通行证。问题是当我将 .jar 插入具体应用程序并运行 gradle build 时，我得到：
> EXCEPTION FROM SIMULATION: local variable type mismatch: attempt to
> set or access a value of type java.lang.Class using a local variable
> of type java.util.Map$Entry[]. This is symptomatic of .class
> transformation tools that ignore local variable information. ...at

当我设置 proguard 规则时问题开始了：
-dontobfuscate
-optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/*
