二、解决方案

下面这种依赖库的配置方式无法获取到 Gradle 编译相关依赖库 ;

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

添加 google() 和 mavenCentral() 即可 ;

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

完整的 build.gradle 构建脚本如下 :

buildscript {
    repositories {
        jcenter()
        google()
        mavenCentral()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        classpath 'com.android.tools.build:gradle-experimental:0.11.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

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

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

修改完毕后可以正常编译 ;
