带有 Proguard 的 Moshi 没有找到 JsonAdapter 类

Question

我似乎无法弄清楚这个问题......

我尝试了各种方法来保留所需的类并搜索了很长时间以找到解决方案....

当我应用 pro Guard 时，应用程序因此错误而崩溃。

我将改造 2.9.0 和 moshi 1.13.0 与 moshi-kotlin 1.13.0 一起使用

原因：java.lang.ClassNotFoundException：找不到类 ApiResponseJsonAdapter

ApiResponse 是具有通用类型的模型

@Keep
@JsonClass(generateAdapter = true)
data class ApiResponse<T>(
    @Json(name = "detail")
    val message: String,
    @Json(name = "result")
    val result: T
)

我需要帮助。 提前致谢。

更新 这是我的职业后卫

我已经解决了这些问题。 我意识到来自 Moshi 的 Kotlin-codegen 工件没有生成，所以我从终端运行 gradle build 并发现对于 Moshi 需要使用 Java 16，但我使用的是默认的 Android Java。 切换后一切都像魅力一样进行了各种修复，例如

包括以下对属性进行分级的语句。

android.jetifier.ignorelist=moshi-1.13.0
