android - "can' t find referenced class"with Proguard and Kotlin

Question

我在使用 proguard 和 kotlin 时遇到了一个奇怪的问题。我正在逐渐将一个 proguarded 项目转换为 kotlin - 到目前为止效果很好，但是在转换某些类时我遇到了 proguard 错误。我还不能分离出这些类的特殊属性是什么，所以它坏了——它们似乎与其他类没有什么不同。例如 InputStreamWithSource 只是:

package org.ligi.passandroid.model

import java.io.InputStream

class InputStreamWithSource(val source: String, val inputStream: InputStream)

它完全可以在 IDE 中运行——我可以部署到设备上——而且所有 UI 测试都运行良好。就在尝试 assembleRelease 项目时，我遇到了我不明白的 proguard 错误:

当我在 proguard 配置中为这些类添加 dontwarn 时，它会在运行时崩溃 - 所以这些类确实被删除了 - 但它们不应该在使用时被删除。

我可以通过在 proguard-config 中为这些类添加 keep class/enum 来解决这个问题 - 但问题是为什么这些类需要这样做 - 恕我直言，它不应该是必需的

任何人都知道什么可能导致此问题或如何最好地调查此问题？完整来源在这里:https://github.com/ligi/PassAndroid

我会确保我在 proguard 中定义了自己的包 - 如下所示:

-dontwarn org.ligi.passandroid.**
-keep class org.ligi.passandroid.** { *; }
