这是我们的R8版本

当前版本是：1.4.94（从 go/r8bot 构建 390954928f0db9c3b888a367f7f128ce3bbfb160 (luci-r8-ci-archive-0-5g74)）。

当我从

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

到

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

我们收到以下错误。

当我想发布我的应用程序时出现此错误：com.android.tools.r8.internal.jb: Sealed classes are not supported as program classes when generating class files

• Android Studio：Flamingo 2022.2.1（我也尝试2022.3.1 Giraffe）
• Gradle版本：8.0（我也尝试8.1和8.0.2）
• Gradle 插件版本：8.0.0
• JDK：17.0.6（嵌入式 Android Studio Flamingo）

在 build.gradle 中，由于 android studio min gradle，我无法编辑编译版本。

compileOptions {
    sourceCompatibility = JavaVersion.VERSION_17
    targetCompatibility = JavaVersion.VERSION_17
  }
  kotlinOptions {
    jvmTarget = "17"
  }

我在模块中使用的密封类是

compileOptions {
    sourceCompatibility = JavaVersion.VERSION_17
    targetCompatibility = JavaVersion.VERSION_17
  }
  kotlinOptions {
    jvmTarget = "17"
  }

我安装了新版本的 Android Studio 并更新了我的项目（不更改依赖项），但遇到了以下问题：

我正在编写 Android 库，所以我想保留一些构造函数/方法的参数名称。我正在将我的库部署为 AAR 文件。

Gradle 从 3.3.2 升级到 3.4.0 后，构造函数和公共方法中的所有参数都被重命名为类似“var1”的名称，在此之前一切都很好。

据我了解，主要区别在于，现在默认使用 R8 而不是 Proguard 来缩小和混淆我们的代码。所以可能我在配置中遗漏了一些东西。

假设我有课：

public class Foo {
    public String bar;

    public Foo(String bar) {
        this.bar = bar;
    }
}

所以在 proguard-rules.pro 中我有：

-keepparameternames
-keepattributes MethodParameters
-keepattributes Signature

-keep class my.class.path.Foo { *; }

我将该配置加载到我的模块 gradle 文件中：

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}}

现在我的 AAR 文件中的类看起来像这样 ->

public class Foo {
    public String bar;

    public SecureElement(String var1) {
        this.bar = var1;
    }
} …

我创建了两个 aar 库：com.example:test1:1.0.0 和 com.example:test2:1.0.0。我将这些库添加到我的主应用程序中，并且在构建 Android-Studio 后抛出错误：

Duplicate class com.example.utils.a found in modules classes.jar (com.example:test1:1.0.0) and classes.jar (com.example:test2:1.0.0)

我发现发生这个错误是因为两个库在同一个包（com.example.utils）中都有类，并且在混淆后 R8 创建了具有相同全名的类（a.class）（我在 aar 的 classes.jar 中看到了这个）。如果我在我的库的属性中禁用 R8，这个错误就会消失。

'a' 不是库类：混淆后所有库类名称保持不变，并且 a.class 被 R8 添加到包中。我阅读了 R8 文档，但没有发现有关此问题的任何信息。有没有办法解决这个问题，而无需在我的一个库中命名包？

我正在使用 Android-R8 并且存在以下 R8 警告：

我正在使用proguard来混淆我的代码，并且我有一个称为库的模块，在该模块中我有一个资产文件夹，并且我保留了一些在运行时使用的 jar。我想将该资产文件夹保留在混淆器中。

这是它的结构：

我怎样才能保留这些？或者我们如何在ProGuard中传递文件的路径？

我在启用 R8 的情况下构建发布 apk 时遇到以下错误：

我最近将 Android 应用程序项目中的 Android Gradle 插件从版本 7.4.2 升级到 8.0.2。但是，当执行 minifyReleaseWithR8 任务时，我现在在发布构建期间遇到错误。

我收到的错误消息如下：

Task :app:minifyReleaseWithR8
AGPBI: {"kind":"error","text":"Library class android.test.AndroidTestRunner extends program class junit.runner.BaseTestRunner","sources":[{}],"tool":"R8"}
Library class android.test.AndroidTestRunner extends program class junit.runner.BaseTestRunner

AGPBI: {"kind":"error","text":"Library class android.test.InstrumentationTestCase extends program class junit.framework.TestCase","sources":[{}],"tool":"R8"}
Library class android.test.InstrumentationTestCase extends program class junit.framework.TestCase

Task :app:minifyReleaseWithR8 FAILED

该错误似乎与缺少服务类以及库类和程序类之间的冲突有关。

这些错误是在我更新 Android Gradle 插件后才开始出现的。我已尝试清理项目并确保所有依赖项都是最新的，但问题仍然存在。

有其他人在升级到 Android Gradle Plugin 8.0.2 时遇到过类似的问题吗？如何解决这些错误并成功缩小 R8 的发布版本？

任何帮助或建议将不胜感激。谢谢你！
