Android Studio 说“无法解析外部依赖项，因为没有定义存储库”，尽管我已经定义了存储库

Question

我从旧版本的 eclipse 导入了一个应用程序，在修复了 build.gradle 的所有问题后，我尝试运行该应用程序，但 Android Studio 说：

Execution failed for task ':processDebugResources'.
> A failure occurred while executing com.android.build.gradle.internal.res.LinkApplicationAndroidResourcesTask$TaskAction
   > Could not isolate value com.android.build.gradle.internal.res.LinkApplicationAndroidResourcesTask$TaskWorkActionParameters_Decorated@ab68ed4 of type LinkApplicationAndroidResourcesTask.TaskWorkActionParameters
      > Could not resolve all files for configuration ':detachedConfiguration3'.
         > Cannot resolve external dependency com.android.tools.build:aapt2:8.3.2-10880808 because no repositories are defined.
           Required by:
               project :

Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

但是我当然定义了存储库。

这是我的 build.gradle 文件：

buildscript {
    repositories {
        google()
        mavenCentral()
        mavenLocal()
        maven { url "https://jitpack.io" }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:8.3.2'
        fileTree(dir: 'libs', include: '*.jar')
    }
}
apply plugin: 'com.android.application'

android {
    defaultConfig {
        compileSdk 21
    }

    namespace "com.example.app"
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        androidTest .setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}
dependencies {
    //implementation 'com.android.tools.build:aapt2:8.3.2-10880808'
}

现在我有 4 个存储库，但使用 Google 存储库应该可以工作。我尝试将依赖项添加到依赖项中，但错误最终是相同的。

有什么想法吗？我错过了什么吗？而且我也不知道这个依赖用在哪里。

P.D.：这是我的第一篇文章，如果我的解释有点混乱，请告诉我，
