无法解决：com.android.support

Question

我第一次构建新的Android Studio项目时得到了Failed to resolve: com.android.support。我知道SO上有几个类似的问题，但这些解决方案似乎都不适合我。

不确定这是否相关，但请注意错误只是Failed to resolve: com.android.support而不是Failed to resolve: com.android.support:appcompat-v7:...或其他一些Android支持库包。

这是我认为相关的代码位。

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
compileSdkVersion 26
buildToolsVersion "26.0.2"
defaultConfig {

    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }

顶级构建文件（Android studio版本＆gt; 3）

buildscript {
ext.kotlin_version = '1.1.61'
repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'
    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 {
    google()
    jcenter()
}
}

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