当我尝试构建我的颤振应用程序时，我遇到了问题：

无法确定任务“:app:compileDebugJavaWithJavac”的依赖关系。

无法解析配置“:app:debugCompileClasspath”的所有任务依赖项。无法解析 com.google.android.gms:play-services-location:16.+。要求：项目 :app > 项目 :location > 无法列出 com.google.android.gms:play-services-location 的版本。> 无法从https://google.bintray.com/exoplayer/com/google/android/gms/play-services-location/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-location/maven-metadata.xml”。> 无法获取“https://google.bintray.com/exoplayer/com/google/android/gms/play-services-location/maven-metadata.xml”。从服务器收到状态代码 403：禁止

我已经尝试了一切，但没有任何效果：

1- 我有一个稳定的互联网连接

2- 我尝试更新或降级 com.android.tools.build:gradle 版本

3- 我试过清理缓存

4- 我试过删除所有的 firebase 库

5- 我用 mavenCentral() 替换了 JCentre()

有我的 android -> build.gradle 文件：

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.2'
    }
}

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

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

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

这是我的 android 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'
}

apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

android {
    compileSdkVersion 28

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        applicationId "io.bujupah.hestia"
        minSdkVersion 17
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        multiDexEnabled true
    }

    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
            storePassword keystoreProperties['storePassword']
        }
    }
    buildTypes {
        release {
            signingConfig signingConfigs.release
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation 'com.google.android.gms:play-services-auth:16.0.1'
    testImplementation'junit:junit:4.12'
    testImplementation 'org.mockito:mockito-core:2.17.0'
    implementation 'com.android.support:multidex:1.0.3'
}

最后我的颤振医生结果：
