Android Moshi KotlinJsonAdapterFactory在启用缩小后无法解析Json

我开发了一个Android应用程序，使用Moshi作为其依赖项之一

今天我想为这个项目启用minify。因此，我在我的

build.gradle

中设置了

minifyEnabled true

之后，我发现来自服务器的所有响应都变为空

首先，我使用Reformation2调用API。

Response.body（）

中的JSON主体不为null，并且具有正确的值

响应主体如下（简化）：

我正在使用下面的代码将其转换为我自己的对象：

val someResponse = Moshi.Builder().add(KotlinJsonAdapterFactory()).build().adapter(SomeResponse::class.java).fromJson(theJsonString)

而

SomeResponse

的代码：

class SomeResponse {
    @Json(name="status")
    var status: String? = null

    @Json(name="data")
    var data: User? = null
}

然后我简单地使用

Log.I（“Moshi”，“${someResponse.status}”）查看值，结果是
null

我已经包括了Moshi Github自述部分中指定的proguard规则，即和

为什么以及如何解决这个问题

以下是我完整的
proguard规则。pro

# Add project specific ProGuard rules here.
