Kotlin反映proguard的SmallSortedMap [英] Kotlin reflect proguard SmallSortedMap

问题描述

我收到这些警告，这些警告破坏了我在任务 transformClassesAndResourcesWithProguardForAppRelease 上发布的版本.

我知道我可以通过使用 -dontwarn 来忽略警告或通知Proguard不发出警告，但是我想知道是否还有其他人遇到了这个问题，并且确实找到了正确的解决方法.>

我正在使用Kotlin版本 1.1.4-2

解决方案

从问题 KT-7652 :

无论如何，目前预计会混淆 kotlin.* 时的反射失败.我们可以做的是为Proguard制定一套有用的规则，以最小化反射库的二进制大小.

因此，目前没有正确的解决方法.

I'm getting these warnings which break my release build on the task transformClassesAndResourcesWithProguardForAppRelease.

I know I can just ignore the warnings or inform proguard to not warn by using -dontwarn but I was wondering if anyone else had come across this and had actually found the correct fix.

I'm using Kotlin version 1.1.4-2

解决方案

Quoting Alexander Udalov from issue KT-7652:

In any way, reflection failures when kotlin.* is obfuscated are expected at the moment. What we can do is work on a useful set of rules for proguard to minimize the binary size of the reflection library.

So there is no correct fix at the moment.
