java - 下载 Gradle 时 Ionic 构建 Android 错误

Question

我对 Ionic 框架很陌生 :)

>npm install -g cordova
>npm install -g ionic
>ionic start test blank
>cd test
>ionic platform add android

当我使用 '>ionic build android' 开始下载 gradle，但我无法下载并出现错误。

是什么导致了这个错误，我该如何解决？!

我下载 Gradle 并将其安装在 PC 上，但它想再次下载。 我可以离线将 Gradle 添加到项目中吗？

Answer 1

我正在使用 Ionic 版本 1.7.14 和以下文件中的 distributionUrl。 myApp/platforms/android/cordova/lib/builders/GradleBuilder.js.

我必须按照此答案中的指定指向本地下载的 gradle。

我遇到了同样的问题。我离线添加了 gradle 到我的项目中。

从发布的链接(这里是 http://services.gradle.org/distributions/gradle-2.2.1-all.zip )下载 gradle 后，将其粘贴到 myApp\platforms\android\gradle\gradle-2.2.1-all.zip 和 build.js 之类的地方从 myApp\platforms\android\cordova\lib\build.js 找到这个:

var distributionUrl = 'distributionUrl=http\\://services.gradle.org/distributions/gradle-2.2.1-all.zip';

并将其替换为您自己的文件位置:

var distributionUrl = 'distributionUrl=../gradle-2.2.1-all.zip';
