Flutter：任务 ':app:checkDebugAarMetadata' 执行失败。无法解析配置“：app：debugRuntimeClasspath”的所有文件

Question

我有一个运行良好的应用程序，但在更新到最新版本的 flutter 后 2.8.1 它开始显示有关 gradle 个文件的错误。

错误是：

FAILURE: Build failed with an exception.

如您所见，android studio 无法在线找到某些文件，但实际上当我按照错误中提供的链接进行操作时，我可以下载这些文件，但 .zip 格式无法下载.aar

现在遇到这样的错误，我通常会手动下载文件，然后将它们放在各自的文件夹中，我们可以从错误中找到它自己，例如：

如果我们查看第一个文件 core-1.6.0.aar，我们可以看到它的文件夹是 androidx.core\core.6.0 并且在该文件夹内 android studio 会生成另一个文件夹，其中包含随机名称如 7664385a7e39112b780baf8819ee880dcd3c4094，所以完整路径如下：

C:\Users\%USERNAME%\.gradle\caches\modules-2\files-2.1\androidx.core\core.6.0\<here goes the folder with the random name>

但是上面提到的文件android工作室没有生成任何文件夹，所以我不知道如何处理它们，我应该把它们放在哪里？或者有什么方法可以解决并消除错误？

我的 android\app\build.gradle 文件：

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

}

allprojects {
    repositories {

    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

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

提前致谢。

我昨天遇到了这个问题。 3小时后。我找到了一个方法。关闭 Android Studio 和
删除 C:\Users\<USER>\.gradle 文件夹（或重命名）

并使用良好的 VPN 重建项目

我更喜欢使用 Cisco Any connect 协议的 VPN。

这是我的 build.gradle，我添加了一些存储库，可能对您有所帮助。

buildscript {
    repositories {
//        google()
//        mavenCentral()
        mavenCentral()
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.0.0'
        classpath 'com.google.gms:google-services:4.3.10'
    }
}

allprojects {
    repositories {
//        google()
//        mavenCentral()
        mavenCentral()
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
    project.evaluationDependsOn(':app')
}

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