问题描述

我刚刚安装了新版本的Android Studio，并尝试使用内置模板创建一个项目.

I just installed a new version of Android Studio and am trying to create a project using the built in templates.

我的环境是: Windows 7，SP1，64位 在安全的域环境中，我是计算机上的域管理员.

My environment is: Windows 7, SP1, 64 bit In a secure domain environment and I am a domain administrator on my machine.

这是我所看到的:

推荐答案

此解决方案对我有用...

This solution worked for me...

在项目目录中找到文件 gradlew.bat ，在该文件中，更改 DEFAULT_JVM_OPTS 变量，如下所示:

Find the file gradlew.bat on your project directory, in that file change DEFAULT_JVM_OPTS variable as below:

set DEFAULT_JVM_OPTS=-Dhttp.proxyHost=YOUR_HOST -Dhttp.proxyPort=PORT -Dhttp.proxyUser=USERNAME -Dhttp.proxyPassword=PASSWORD -Dhttps.proxyHost=YOUR_HOST -Dhttps.proxyPort=PORT -Dhttps.proxyUser=USERNAME -Dhttps.proxyPassword=PASSWORD

然后运行gradlew clean build.
