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

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';

Answer 2

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

Answer 3

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

Answer 4

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...

Answer 5

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

Answer 6

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';
