我真的不知道该如何为 Android 构建 Ionic

系统信息

Cordova CLI: 5.3.3
Ionic Version: 1.1.0
Ionic CLI Version: 1.7.7
Ionic App Lib Version: 0.6.3
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Mac OS X El Capitan
Node Version: v0.12.6
Xcode version: Xcode 7.0.1 Build version 7A1001 

当我运行

$ ionic build android

它会产生

我尝试更改 var distributionUrl = 'distributionUrl=http\\://services.gradle.org/distributions/gradle-2.2.1-all.zip'; 以将其指向本地分发，但它不会查看指定的路径，而是查看项目的 android 目录。

当我使用 Ant 构建时

cordova build android -- --ant

它构建成功，但我无法按照文档建议的方式进行构建。
