Retrofit + RxJava：java.lang.IllegalArgumentException：找不到f.e <b.v>

Question

我对Retrofit + rx和ProGuard存在严重问题。

1. App适用于调试
2. 应用程序在发布时使用minifyEnabled false
   
3. 应用程序在发布时使用minifyEnabled true和useProguard 假
   
4. 应用程序无法在发布时使用minifyEnabled = true

此代码是如何创建Retrofit：

@Provides @Singleton Retrofit provideRetrofit(Call.Factory factory, Environment environment) { //A Gson formatter to covert string in date Gson gson = new GsonBuilder() .setDateFormat("yyyy-MM-dd'T'HH:mm:ssZ") .create(); return new Retrofit.Builder() .baseUrl(environment.getBaseUrl()) .callFactory(factory) .addConverterFactory(GsonConverterFactory.create(gson)) .addCallAdapterFactory(RxJava2CallAdapterFactory.create()) .build(); }

这是我的ProGuard：

令人困惑，抱歉，但我尝试了所有解决方案。

我有这个例外：
