的ProGuard使得GSON回報LinkedTreeMap，而不是我喜歡的類型的

Question

下面的代碼行爲我工作正常：

val users: Array<Catalog> = com.google.gson.Gson().fromJson(data, Array<MyUserClass>::class.java)

但是，當我讓ProGuard的，我得到這個錯誤：

java.lang.ClassCastException: com.google.gson.internal.LinkedTreeMap cannot be cast to com.example.app.Models.MyModel

MyUserClass如下：

data class MyUserClass(var posts: List<UserPosts>)

所以GSON正確使users是MyUserClass - 但不是MyUserClass是的UserPosts列表，它最終被的LinkedTreeMap

我一直在試圖解決現在這一段時間的列表，以及所有的答案我發現與此相關的必須與泛型有關，但我不使用泛型，我直接將該類傳遞給Gson。

我完全失去了在這一點上，因此任何指導，將apprecciated

下面是相關的ProGuard規則：

##---------------Begin: proguard configuration for Gson ---------- 
# Gson uses generic type information stored in a class file when working with fields. Proguard 
# removes such information by default, so configure it to keep all of it. 
-keepattributes Signature 

# For using GSON @Expose annotation 
-keepattributes *Annotation* 

# Gson specific classes 
-keep class sun.misc.Unsafe { *; } 
#-keep class com.google.gson.stream.** { *; } 

# Application classes that will be serialized/deserialized over Gson 
-keep class com.google.gson.examples.android.model.** { *; } 

-keep class com.example.Models.** { *; } 

# Prevent proguard from stripping interface information from TypeAdapterFactory, 
# JsonSerializer, JsonDeserializer instances (so they can be used in @JsonAdapter) 
-keep class * implements com.google.gson.TypeAdapterFactory 
-keep class * implements com.google.gson.JsonSerializer 
-keep class * implements com.google.gson.JsonDeserializer 
##---------------End: proguard configuration for Gson ---------- 

-keep public class MyUserClass 
-keep public class UserPosts

確保您proguard.cfg包含了所有的規則：

##---------------Begin: proguard configuration for Gson ---------- 
# Gson uses generic type information stored in a class file when working with fields. Proguard 
# removes such information by default, so configure it to keep all of it. 
-keepattributes Signature 

# For using GSON @Expose annotation 
-keepattributes *Annotation* 

# Gson specific classes 
-keep class sun.misc.Unsafe { *; } 
#-keep class com.google.gson.stream.** { *; } 

# Application classes that will be serialized/deserialized over Gson 
-keep class com.google.gson.examples.android.model.** { *; } 

# Prevent proguard from stripping interface information from TypeAdapterFactory, 
# JsonSerializer, JsonDeserializer instances (so they can be used in @JsonAdapter) 
-keep class * implements com.google.gson.TypeAdapterFactory 
-keep class * implements com.google.gson.JsonSerializer 
-keep class * implements com.google.gson.JsonDeserializer 

##---------------End: proguard configuration for Gson ---------- 
-keep public class MyUserClass 
-keep public class UserPosts
