与Proguard和Kotlin一起“找不到引用的课程”

Question

我和proguard和kotlin有一个奇怪的问题。 我正在逐步将一个项目转换为kotlin - 到目前为止它已经非常好了，但是在转换某些类时我遇到了proguard错误。 我还不知道这些类的特殊属性是什么，所以它打破了 - 它们似乎与其他类没有什么不同。 作为示例，InputStreamWithSource只是：

package org.ligi.passandroid.model

import java.io.InputStream

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

它完全适用于IDE - 我可以部署到设备 - 所有UI测试都运行良好。 只是在尝试组装时释放项目我得到了proguard错误我不明白：

当我在proguard配置中为这些类添加dontwarn而不是在运行时崩溃时 - 所以这些类实际上被删除了 - 但是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些 - 恕我直言，它不应该被需要

任何人有一些想法可能导致这个或如何最好地调查这个问题？ 完整的来源是： https ： //github.com/ligi/PassAndroid

我会确保我在proguard中定义了自己的包 - 类似这样：

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