Question

我绝对是Android Studio的新手，并且正在学习在线课程。我尝试运行给出的赋值，只是得到以下错误：

错误：无法解析外部依赖项com.android.tools.build:gradle:1.5.0，因为未定义存储库。要求：作业1：app：未指定

我尝试运行空白活动并将gradle版本复制到gradle构建文件中，但仍然出现上述错误。

这是我为作业分配的gradle.build：

ext {
var = '3.4.2'
}// Top-level build file where you can add configuration options common 
 to all sub-projects/modules.


buildscript {
repositories {
    jcenter()
    maven {
        url 'https://maven.google.com'
    }
    maven { url 'https://maven.fabric.io/public' }

}
dependencies {
    classpath "com.android.tools.build:gradle:3.4.2"

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}

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

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


task _projectZip(type:Zip) {
description = 'Makes a zip file of your project that can be properly 
shared with others.'
from projectDir
baseName = project.name

我认为这是我的应用程序级别gradle文件：
