使用 proguard 将 kotlin 升级到 1.5.20 时，Moshi 1.12.0 反射失败

Question

它在 kotlin 1.4.31 上运行良好。升级kotlin到1.5.20后，打开APP一直闪退。错误是

我尝试根据moshi更新混淆器github，但问题仍然存在。

# JSR 305 annotations are for embedding nullability information.
-dontwarn javax.annotation.**

-keepclasseswithmembers class * {
    @com.squareup.moshi.* <methods>;
}

-keep @com.squareup.moshi.JsonQualifier @interface *

# Enum field names are used by the integrated EnumJsonAdapter.
# values() is synthesized by the Kotlin compiler and is used by EnumJsonAdapter indirectly
# Annotate enums with @JsonClass(generateAdapter = false) to use them with Moshi.
-keepclassmembers @com.squareup.moshi.JsonClass class * extends java.lang.Enum {
    <fields>;
    **[] values();
}

# Keep helper method to avoid R8 optimisation that would keep all Kotlin Metadata when unwanted
-keepclassmembers class com.squareup.moshi.internal.Util {
    private static java.lang.String getKotlinMetadataClassName();
}

有没有人有同样的问题或任何建议？

将 gradle 插件升级到 4.2.2 后。反射问题已修复。（但在启用 proguard 时仍然无法解析 Retrofit2 响应。继续尝试..）

使用 proguard 将 kotlin 升级到 1.5.20 时，Moshi 1.12.0 反射失败

Moshi 1.12.0 reflection failed when upgrade kotlin to 1.5.20 with proguard
