與Proguard和Kotlin一起“找不到引用的課程”

Question

我和proguard和kotlin有一個奇怪的問題。 我正在逐步將一個項目轉換為kotlin - 到目前為止它已經非常好了，但是在轉換某些類時我遇到了proguard錯誤。 我還不知道這些類的特殊屬性是什么，所以它打破了 - 它們似乎與其他類沒有什么不同。 作為示例，InputStreamWithSource只是：

package org.ligi.passandroid.model

import java.io.InputStream

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

它完全適用於IDE - 我可以部署到設備 - 所有UI測試都運行良好。 只是在嘗試組裝時釋放項目我得到了proguard錯誤我不明白：

當我在proguard配置中為這些類添加dontwarn而不是在運行時崩潰時 - 所以這些類實際上被刪除了 - 但是它們不應該在使用時被刪除。

我可以通過在proguard-config中為這些類添加keep class / enum來解決這個問題 - 但問題是為什么這些類需要這些 - 恕我直言，它不應該被需要

任何人有一些想法可能導致這個或如何最好地調查這個問題？ 完整的來源是： https ： //github.com/ligi/PassAndroid

我會確保我在proguard中定義了自己的包 - 類似這樣：

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