ANDROID_HOME=D:\DevTools\Android\Android_SDK_NDK\android-sdk
JAVA_HOME=C:\Program Files\Java\jdk1.7.0_45

i generated a cordova project

OS:           Windows 7 6.1 x86

may be this was due to my office firewall/proxy which is not allowing to download the zip file. but i have the zip file extracted and set the path variable as

GRADLE_HOME = C:\gradle-2.2.1

even that also i'm not able to resolve this issue. I understand that the env. path variable is not accepted in build script but i'm not sure where to change or by-pass this step.

Answer 1

As you mentioned, it looks more like a network issue. The gradle download will fail if you are using restricted proxy network. In case of network restrictions, you can work around this issue by following the steps below:

1) Download the required gradle version zip file from gradle distribution link and save it in local folder.

2) Navigate to PROJECT_ROOT_FOLDER/platforms/android/cordova/lib/builders folder and edit GradleBuilder.js file

3) Change the line from var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'http\\://services.gradle.org/distributions/gradle-2.2.1-all.zip'; to 'var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'file:///local/path/to/folder/where/gradle/zip/is/saved/gradle-2.2.1-all.zip'; and save the file

4) Try rebuilding android build.

You can also try the following as quick fix,

1) In command prompt execute the following command: export CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL=file:///local/path/to/folder/where/gradle/zip/is/saved/gradle-2.2.1-all.zip

2) Execute the following command: cordova run android

Answer 2

You need to set the gradle proxy by adding these lines to ~/.gradle/gradle.properties (create the file if it does not exist):

systemProp.http.proxyHost=myproxy.com
systemProp.http.proxyPort=123
systemProp.https.proxyHost=myproxy.com
systemProp.https.proxyPort=123

Substitute your proxy and port, of course.
