android - google-play-services-maps:17.0.0即使使用默认项目Android Studio创建也不起作用

Question

请帮我...

我想创建一个基于Google Maps的项目。但是在Android Studio中构建gradle之后，会发生以下错误:

错误:

Failed to resolve: com.google.android.gms:play-services-maps:17.0.0
Install Repository and sync project
Show in Project Structure dialog
Affected Modules: app

当我单击“安装存储库并...”时，出现此消息:

找不到依赖项“com.google.android.gms:play-services-maps:17.0.0”

注意:
Gradle 工作在线模式。
我去了Setting and Android SDK然后下载了Google Play服务..但是它对我不起作用。
我还设置了代理。

编辑:

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 28
    buildToolsVersion "29.0.3"
    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion 15
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.core:core-ktx:1.2.0'
    implementation 'com.google.android.gms:play-services-maps:17.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.2.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

根gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.3.31'
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        google()

    }
}

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

经过大量的努力，我得以解决问题。
看起来很奇怪，问题是通过手动调整代理解决的。

谢谢大家
