无法查询属性“packageName”的值清单文件不存在：

如何解决无法查询属性“packageName”的值清单文件不存在：

编辑：解决方法

我可以使用 ./gradlew :app:assembleRelease 构建我的应用程序，但这实际上并不能解决问题，它只是一种解决方法。之后，我在 /app/build/outputs/apk/release 中找到 apk 并使用 apksigner 在终端中手动签署 apk。如果有人正在阅读这篇文章：并且没有找到此问题的解决方案，则这是一种有效的解决方法（尽管它不是解决方案）。要手动对 apk 进行签名，请搜索“从命令行构建您的应用”，然后会出现一个解释如何执行此操作的 Android 开发者页面。

每次我尝试构建时，它都会执行“:generateDebugBuildConfig”而不是“app:generateDebugBuildConfig”。

Execution failed for task ':generateDebugBuildConfig'.
> Failed to calculate the value of task ':generateDebugBuildConfig' property 'buildConfigPackageName'.
   > Failed to query the value of property 'packageName'.
      > Manifest file does not exist: /home/android-studio/Documents/your_android_app/src/main/AndroidManifest.xml

这个问题似乎和这个完全一样：

Cannot Read packageName ':generateDebugBuildConfig'

然而，没有答案。

清单文件指向错误的方向：

/home/android-studio/Documents/your_android_app/src/main/AndroidManifest.xml

代替

/home/android-studio/Documents/your_android_app/app/src/main/AndroidManifest.xml

这是因为构建运行的是“:generateDebugBuildConfig”而不是“:app:generateDebugBuildConfig”

除了我链接到的问题（没有解决方案）之外，我在互联网上找不到任何关于此的信息。

It is NOT THIS BUG，那个显示在图形用户界面中，而这个显示在构建输出中。 （另外，我尝试了那里的大部分解决方案，它们都不起作用）。

此外，我可以完美地运行我的应用程序，似乎我可以运行模块“app”，这解决了问题。

Image showing the run configurations that do not apply to build for some reason

我根本无法为 Build 执行此操作，因此我无法使用它。问题是如果构建不起作用，我将无法生成签名的 apk。

感谢大家的帮助。

解决方法

在您附加的第一个代码中（根配置中的 build.gradle）。有一个 android 配置。尝试删除它，我的意思是该文件应该只包含：

buildscript {
    ext.kotlin_version = "1.4.20"
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.1.1"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

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

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io"}
    }
}

另外，尝试使用以下命令或仅使用 android studio 中的 clean 选项清理项目：

./gradlew clean

最后验证一下这个项目有没有别的包名？或者您更改了该包名称？

注意事项：

如果此存储库是公开的，请附加它以进行更好的调试。
