Question

我的 Android 项目过去构建时没有任何问题。而且我没有更改代码。但现在我有这个错误。我将 Android Studio 更新到版本 202.7188722 并创建了一个没有任何活动的新项目，但我再次收到此错误：

Execution failed for task ':app:checkDebugAarMetadata'.
> Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
> Could not find viewpager2-1.0.0.aar (androidx.viewpager2:viewpager2:1.0.0).
 Searched in the following locations:
     https://dl.google.com/dl/android/maven2/androidx/viewpager2/viewpager2/1.0.0/viewpager2- 
1.0.0.aar

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

注意：我测试了互联网连接和 HTTP 代理，没有问题。

这些是我的新项目 gradle 文件：

<块引用>

项目：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
    google()
    mavenCentral()
}
dependencies {
    classpath "com.android.tools.build:gradle:4.2.0-beta06"

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

allprojects {
repositories {
    google()
    mavenCentral()
    jcenter() // Warning: this repository is going to shut down soon
}
}

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

我遇到了同样的问题。在我的情况下，它来自代理和连接问题。确保您的代理工作正常。

找不到 viewpager2-1.0.0.aar (androidx.viewpager2:viewpager2:1.0.0)
