Android Studio 3.14正式版学习，不能编译问题求助

[pfworld]

我建立了一个默认项目，就是不能启动报一下错误

Required by:
project :
Add Google Maven repository and sync project
Open File
Enable embedded Maven repository and sync project

什么代码都没有，就是默认项目，一直不能启动，按照网上教程设置了gradle路径，设置了代理，就是不能启动

build:gradle文件

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

buildscript {
    
    repositories {
        //google()
        jcenter()
        maven { url "http://maven.springframework.org/release" }
        maven { url "http://maven.restlet.org" }
        mavenCentral()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'
        

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

allprojects {
    repositories {
        //google()
        jcenter()
        maven { url "http://maven.springframework.org/release" }
        maven { url "http://maven.restlet.org" }
        mavenCentral()

    }
}

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

Android Studio 3.14正式版官方安装版

[Non-satisfied]

把那两个google()的注释去掉，然后执行Sync Project with Gradle Files 试下，不行再试下执行Make Project。

[pfworld]

取消变成另外一个错了，我在安装网上的加上注释的

我的setting设置：C:/Users/Administrator/.gradle/wrapper/dists/gradle-4.4-all/9br9xq1tocpiv8o6njlyu5op1/gradle-4.4

可以保证这个是自行下载的，我按照网上解决方案添加的

取消“google()”注释就变成一下错误了，整了一天了，新建默认项目都启动不起

Connection timed out: connect

而这个错误的解决方法，我已经参考网上资料进行设置了，就是解决不了问题！我第一次下载的是“Android Studio 3.2正式版”,因为这个问题重新下载的3.1.4版本，SDK是最新的。gradle是自行下载的。

[pfworld]

Download https://dl.google.com/dl/android/maven2/com/android/support/appcompat-v7/maven-metadata.xml Running for 9s

下载这个老失败！

[pfworld]

是要做一个本机代理吗？Android Studio太不好用了，环境不好配！

[Koiier]

我建议你用androidstudio 2.3，新版本的很多东西都取消了

[zbdzjx]

maven中增加下面这句，放在前面。
maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}

gradle-4.4，实在不行，就手工下载，再放到需要的位置。

4.4下载成功了！但是就是运行不起来！这个也试了！郁闷的很！

Android studio 在哪下载

[r00_a2lBUR]

为什么不用3.21版？我前几天下载了这个版本，一路安装，新建工程就可以编译运行了
