Ionic build Android error when downloading Gradle

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?

Solution 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';

Solution 2:

Since the solution posted above needs to include .zip into folder that is about 55MB

You can also force CLI to use Ant instead of gradle during a build with the following command:

cordova build android -- --ant

Solution 3:

I ran into this issue as our network proxy is blocking the download of the zip file. Here's what I found:

NOTE: this differs from the "accepted" answer in that we aren't modifying Cordova's library directly. This is far less prone to "error" or being overwritten when you run ionic state restore

Download gradle - http://services.gradle.org/distributions/gradle-2.2.1-all.zip
Put this file in platforms/android/gradle. However, if you're integrating this into your build process, you may want to stick it somewhere less volatile and add a step to copy the file into that location.
Set the environment variable CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL to ../gradle-2.2.1-all.zip
- linux/osx: add export CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL="../gradle-2.2.1-all.zip" to your ~/.bashrc file
- windows: setx CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL ../gradle-2.2.1-all.zip
Run ionic build android

Solution 4:

Another option from command line is to run $ export JAVA_OPTS="-Dhttp.proxyHost=proxy-url.com -Dhttp.proxyPort=911 -Dhttps.proxyHost=secure-proxy-url.com -Dhttps.proxyPort=911"before the cordova build command.

Solution 5:

If you require to use a proxy on your network then add a gradle.properties file in %USER_HOME%/.gradle with the below but replacing the values with your proxy details. This worked for me.

gradlePropertiesProp=gradlePropertiesValue
sysProp=shouldBeOverWrittenBySysProp   
envProjectProp=shouldBeOverWrittenByEnvProp  
systemProp.system=systemValue    
systemProp.http.proxyHost=myproxy.com    
systemProp.http.proxyPort=8080    
systemProp.http.nonProxyHosts=\*.mydomain.com|localhost   
systemProp.https.proxyHost=myproxy.com    
systemProp.https.proxyPort=8080    
systemProp.https.nonProxyHosts=\*.mydomain.com|localhost
