Flutter 构建错误：“无法解析 com.google.android.gms:play-services-ads-base:[19.7.0]。”

Question

最近我在 Flutter 上收到以下构建错误：

无法确定任务 ':app:processDebugResources' 的依赖关系。

无法解析配置“:app:debugRuntimeClasspath”的所有任务依赖项。 无法解析 com.google.android.gms:play-services-ads-base:[19.7.0]。 要求： 项目：app > 项目：google_mobile_ads > com.google.android.gms:play-services-ads:19.7.0 项目：app > 项目：google_mobile_ads > com.google.android.gms:play-services-ads:19.7.0 > com.google.android.gms:play-services-ads-lite:19.7.0 项目：app > 项目：google_mobile_ads > com.google.android.gms:play-services-ads:19.7.0 > com.google.android.gms:play-services-gass:19.7.0 > 无法列出 com.google.android.gms:play-services-ads-base 的版本。 > 无法从 https://google.bintray.com/exoplayer/com/google/android/gms/play-services-ads-base/maven-metadata.xml 加载 Maven 元数据。 > 无法获取资源“https://google.bintray.com/exoplayer/com/google/android/gms/play-services-ads-base/maven-metadata.xml”。 > 无法获取“https://google.bintray.com/exoplayer/com/google/android/gms/play-services-ads-base/maven-metadata.xml”。从服务器收到状态码 502：Bad Gateway

我相信这是由于 bintray 贬值所致。这是我的 android/build.gradle

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        mavenCentral()
        google()

//        jcenter()

//        maven {
//            url 'https://dl.bintray.com/android/android-tools'
//        }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.4'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.10'
    }
}

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

    }
}

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

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

我已将 jcenter 替换为 mavenCentral，清除缓存并运行 flutter clean 但我仍然收到相同的错误

这是我的应用级 build.gradle：

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'
}

            signingConfig signingConfigs.debug
        }
    }

apply plugin: 'com.google.gms.google-services'
// Work around for onesignal-gradle-plugin compatibility
com.google.gms.googleservices.GoogleServicesPlugin.config.disableVersionCheck = 
true
