签名的 APK 构建失败 re:play-services-ads-identifier.properties 冲突

Question

我仅在签名 APK 构建期间遇到构建错误。以前签名的 APK 构建工作没有问题。自上次签署 APK Build 以来唯一的变化是我已更新到新的 Android Studio 3.6 -Build #AI-192.7142.36.36.6200805。

构建输出是： FAILURE：构建失败并出现异常。

• 出了什么问题： 任务 ':app:packageDebug' 执行失败。

  执行 com.android.build.gradle.internal.tasks.Workers$ActionFacade 时发生故障 条目名称“play-services-ads-identifier.properties”发生冲突

build.gradle(:app)

build.gradle(项目)

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()

    }
    dependencies {

        classpath 'com.google.gms:google-services:4.3.3'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

如果我构建一个未签名的 APK：

我不确定如何更新或解决 :app:packageDebug 问题？和/或识别 play-services-ads-identifier.properties 冲突？

Answer 1

我似乎已经通过删除位于 app/debug 目录中的 apk 和 json 文件解决了这个问题。

删除后，签名的APK构建成功完成。

Answer 2

删除app\build\outputs\apk（debug 和 release）目录中的所有文件夹。然后是clean project、rebuild project，最后是Run 你的项目。就我而言，我也面临在模拟器中运行 APK 的问题，我通过这样做解决了它。

Answer 3

通过转到Build -> Clean 清理构建，为我修复了它。

Answer 4

我观察到 gradle 版本的问题：com.android.tools.build:gradle:4.1.0

在项目级别build.gradle文件中将版本升级为4.1.2，如下所示，然后在运行Build->Clean后再次生成apk而没有错误（在我的情况下，只需清理没有版本升级并不能解决错误）：

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.1.2"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
