前言
Android Studio安裝完成割按，新創(chuàng)建或?qū)牍こ烫崾疽韵洛e(cuò)誤信息：
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring root project 'MyApplication'.
> Could not resolve all artifacts for configuration ':classpath'.

意思是說(shuō)無(wú)法訪問(wèn)dl.google.com這個(gè)域名两波，用命令ping這個(gè)域名的確是無(wú)法訪問(wèn)刁赖。實(shí)際上Android 工程的構(gòu)建過(guò)程很多步驟需要訪問(wèn)這個(gè)域名。
解決方法
方式一
修改項(xiàng)目根目錄下的build.gradle文件泞歉，使用國(guó)內(nèi)地址構(gòu)建，如下：
buildscript {
repositories {
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.4.2'
}
}
allprojects {
repositories {
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
}
}
問(wèn)題是解決了匿辩，但對(duì)代碼有侵入且不利于代碼維護(hù)腰耙。
方式二
-
查詢(xún)dl.google.com在國(guó)內(nèi)的可用的鏡像IP地址(http://ip.tool.chinaz.com/)
image.png 修改電腦hosts文件，鏡像國(guó)內(nèi)域名訪問(wèn)铲球，配置如下：
Mac下：Finder->前往->前往文件夾（輸入etc/hosts）：文件拷貝出來(lái)挺庞，打開(kāi)后末尾添加：
203.208.43.71 dl.google.com修改完成后替換hosts文件即可。
Windows訪問(wèn)系統(tǒng)hosts文件稼病，修改方式相同选侨。
