Ionic build Android error when downloading Gradle

Question

I'm very new to the Ionic framework :)

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

When I use '>ionic build android' start download gradle, but I can't download and get an error.

What caused this error and how can I fix it?!

I download Gradle and install it on a PC, but it wants to download again. Can I add Gradle to a project offline?

Answer 1

I am using Ionic version 1.7.14 and the distributionUrl found in the following file. myApp/platforms/android/cordova/lib/builders/GradleBuilder.js.

I had to point the locally downloaded gradle as specified in this answer.

I had the same problem. I added gradle to my project offline.

After downloading gradle from issued link (here is http://services.gradle.org/distributions/gradle-2.2.1-all.zip) paste it in somewhere likes myApp\platforms\android\gradle\gradle-2.2.1-all.zip and in build.js from myApp\platforms\android\cordova\lib\build.js find this:

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

And replace it with your own file's location:

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