无法构建 Flutter Android Build：从服务器收到状态代码 502：错误网关

Question

您好，我正在尝试构建我的 flutter 应用程序（调试/发布）。直到昨天一切都很好，但今天从早上开始如果我构建我的应用程序（调试/发布），我将面临以下异常

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':app:processDevDebugResources'.
> Could not resolve all task dependencies for configuration ':app:devDebugRuntimeClasspath'.
   > Could not resolve com.google.android.gms:play-services-location:16.+.
     Required by:
         project :app > project :location
      > Failed to list versions for com.google.android.gms:play-services-location.
         > Unable to load Maven meta-data from https://google.bintray.com/exoplayer/com/google/android/gms/play-services-location/maven-metadata.xml.
            > Could not get resource 'https://google.bintray.com/exoplayer/com/google/android/gms/play-services-location/maven-metadata.xml'.
               > Could not GET 'https://google.bintray.com/exoplayer/com/google/android/gms/play-services-location/maven-metadata.xml'. Received status code 502 from server: Bad Gateway

这些是我的 Flutter 和 Dart 版本：

• 颤振2.5.3
• 飞镖2.14.4

位置插件：

location: ^4.3.0

gradle.properties 中的分发 URL：

distributionUrl=https\://services.gradle.org/distributions/gradle-7.2-all.zip

项目级别等级：

buildscript {
    ext.kotlin_version = '1.4.21'
    repositories {
        google()
        mavenCentral()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.1'
        classpath 'com.google.gms:google-services:4.3.4'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.firebase:firebase-crashlytics-gradle:2.4.1'

    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
        jcenter()
    }
}

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

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

感谢您对我的问题的答复。花了很长时间我找到了解决方案。

我按照以下步骤操作：

将 gradle.properties 文件更新为：

distributionUrl=https\://services.gradle.org/distributions/gradle-6.7-all.zip

将项目级别 build.gradle 文件中的依赖项更新为：

classpath 'com.android.tools.build:gradle:4.0.1'

清洁并获得哈巴狗：

flutter clean
flutter pub get

现在构建您的项目。它成功了。

我想我的问题与 distributionUrl 有关
