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?

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';

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

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

1. Download gradle - http://services.gradle.org/distributions/gradle-2.2.1-all.zip

2. 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.

3. 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

4. Run ionic build android

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.

Cordova 6.0.0 / Visual Studio Code 0.10.6

TL;DR

Manually download http://services.gradle.org/distributions/gradle-2.2.1-all.zip.

Place it in appName\platforms\android\gradle\

set CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL=..\gradle-2.2.1-all.zip

Start code and compile.

Explanation:

GradleBuilder.js sets distributionUrl as follows:

var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'http\://services.gradle.org/distributions/gradle-2.2.1-all.zip';

Script runs in appName\platforms\android\gradle\wrapper

Output is:

Downloading file://appname/platforms/android/gradle/gradle-2.2.1-all.zip

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

Hi all I had the same issue.

In the platforms\android\cordova\lib\build.js file, I changed

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

to

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

and it worked.

There seems to be a problem for the previous solutions. At least none of them worked for me, and I just changed it to:

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

Then it works. I don't know why they all add "distributionUrl=" as follows (this doesn't work for me):

 var distributionUrl = 'distributionUrl=http\\://localhost/gradle-2.2.1-all.zip';

BTW, I am using ionic 2.

Pay attention to the path if you don't want to use localhost. It will automatically add myApp/platforms/android/gradle/wrapper before distributionUrl, for example if you put gradle-2.2.1-all.zip in the myApp/platforms/android/gradle directory, then you need to set:

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

Alternatively, if you have a web server on your localhost, download and put the gradle (exactly the tested version, i.e. http://downloads.gradle.org/distributions/gradle-2.2.1-all.zip at the time of this post) in the www root and change the platforms\android\cordova\lib\build.js file in your application directory to this one:

 var distributionUrl = 'distributionUrl=http\\://localhost/gradle-2.2.1-all.zip';

Changing the URL to a local file (not an http address) would not work for me under windows and it would complain that the URL has an unknown protocol.

I had the same problem, and it was solved with uninstalling build-tools 24, and installing build-tools 23 from SDK Manager.

I have faced the same problem recently, and I searched here and there.

Finally for the latest build I found the solution.

After "ionic platform add android" command, go to platforms/android/cordova/lib/builders/GradleBuilder.js

Search for

http\\://services.gradle.org/distributions/gradle-2.2.1-all.zip

and change it to

http\\://downloads.gradle.org/distributions/gradle-2.2.1-all.zip

All answers here are all saying the same thing when this could be done easier than the top answer. Updating your Android SDK should fix it, and you can do it with this one line from the terminal:

android update sdk --no-ui --all --filter "extra-android-m2repository"

or

android update sdk --no-ui --filter extra

Also see this repos issue (it's the essentially same problem).

But after you do that rebuild, and it should work.

It sounds like Windows Defender or some other antivirus system is messing up with your install. So temporarily deactivate your firewall and re-run the command:

ionic build android (or ios)

At the end you have the message BUILD SUCCESSFUL...

As far as ionic development concern,you will have to modified the distributionURL in GradleBuilder.js with below mentioned URL.

/android/cordova/lib/builders/GradleBuilder.js

var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'https://services.gradle.org/distributions/gradle-2.14.1-all.zip';

I used every thing above but nothing was working and then I did this and boom it worked..!

Here is what I did:

1. open cmd from your project
2. goto https://services.gradle.org/distributions/ click on the version you need , right click and copy link.
3. Once done set the variable : set CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL=https://services.gradle.org/distributions/gradle-2.2.1-all.zip
4. Good to go!

Updating the Android platform did the trick for me:

• Cordova platform update Android
• Cordova prepare,
• Cordova compile and finally
• Cordova build

This is because of a Gradle error.

Download the file http://services.gradle.org/distributions/gradle-2.14.1-all.zip and extract it in any of directory and set the path by open cmd and enter: setx path (extracted directory)/bin

After that, reopen cmd and check whether Gradle is works or not by issuing gradle -v. It shows the Gradle version output. Now the error is fixed; run ionic build android.

Download JDK version 8 and remove all existing versions.

And update Ionic.

I hope your problem will be solved.
