Android Studio更新3.6.3之後出現Could not resolve all artifacts for configuration :classpath. 問題

你是否和我一樣，只因在人羣中多看了他一眼？

再也沒能擺脫**的問題

FAILURE: Build failed with an exception.

CONFIGURE FAILED in 1s

之前Android Stdio還好好的突然出現這種問題，作爲萌新黨很無奈。
明明纔剛進了新手村（第N次進了），卻直接遇到個致命Boss。老手不會遇到，新手不會解決。

看了很多方法，下載證書，換國產鏡像，改本機Host都沒能解決。

後來看到了網站地址 這篇文章第一個方法後才解決了使用的問題。（能跑就行了，要啥自行車。）

那麼問題來了，有這麼簡單的方法要這篇文章幹嘛。

這篇文章爲了解決每次創建新項目時都要手動修改配置的麻煩，提供解決方法。

打開${Android\Android Studio安裝目錄}\plugins\android\lib\templates\gradle-projects\NewAndroidProject\root\build.gradle.ftl 這個文件
${Android\Android Studio安裝目錄}指的是Android Stdio安裝的位置
我是這樣配置的

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

buildscript {
    <#if generateKotlin>ext.kotlin_version = '${kotlinVersion}'</#if>
    repositories {
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        maven { url'https://maven.aliyun.com/repository/public/' }
        maven { url'https://maven.aliyun.com/repository/google/' }
        maven { url'https://maven.aliyun.com/repository/jcenter/' }
        maven { url'https://maven.aliyun.com/repository/central/' }
        mavenLocal()
        mavenCentral()
        <#if includeKotlinEapRepo!false>maven { url '${kotlinEapRepoUrl}' }</#if>
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
        <#if generateKotlin>classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"</#if>

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

allprojects {
    repositories {
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        maven { url'https://maven.aliyun.com/repository/public/' }
        maven { url'https://maven.aliyun.com/repository/google/' }
        maven { url'https://maven.aliyun.com/repository/jcenter/' }
        maven { url'https://maven.aliyun.com/repository/central/' }
        mavenLocal()
        mavenCentral()
        <#if includeKotlinEapRepo!false>maven { url '${kotlinEapRepoUrl}' }</#if>
    }
}

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

然後保存。重新創建一個新項目就能直接用了。
//就這麼小的問題我都要解決一天，嗚嗚嗚~

更新

classpath 'com.android.tools.build:gradle:3.6.1'

也可以使用
