java – gradle build因未知主机异常而失败

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

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

这是我所看到的：

C:\Users\stuz\AndroidStudioProjects\test>gradlew compileDebug --stacktrace

谢谢你的帮助.

解决方法:

问题出在gradle / wrapper / gradle_wrapper.properties文件中.我不确定它是如何发生的,但是你有一个不正确的URL用于Gradle的可下载分发.改变这一行：

distributionUrl=file://C:/Users/stuz/.gradle/wrapper/dists/gradle-1.10-all.zip

对此：

distributionUrl=http\://services.gradle.org/distributions/gradle-1.10-all.zip
