无法使用minifyEnabled

编程问答 2022-08-15

问题描述

当前，我的UI测试在将minifyEnabled设置为false的情况下可以很好地运行以进行调试。但是我希望能够使用minifyEnabled运行我们的UI测试，但出现错误：

令人讨厌的行只是使用Koin进行依赖项注入的BaseUiTest类的第一行：

private val localPrefs: LocalPrefs by inject()

build.gradle文件如下所示：

buildTypes {
  debug {
    minifyEnabled true
    proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),'proguard-rules.pro'
    testProguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),'proguard-test.pro'
  }
}

对于proguard-test.pro文件，我已经尝试了所有可以想到的方法，包括：

-include proguard-rules.pro
-dontobfuscate
-dontwarn
-keepattributes SourceFile,LineNumberTable

我不明白为什么它无法解析Kotlin类LazyKt
