Android builds fail due to missing jcenter dependencies

Several java dependencies appear to be missing from https://jcenter.bintray.com causing the failure of android native builds. As a workaround Ionic Pro Package users can create the following hook script to adjust their build.gradle file. This script should force a check of https://maven.google.com before jcenter allowing for retrieval of the necessary dependencies. 

Create a file named maven_swap.sh in the root of your project.

#!/bin/bash
#remove jcenter
sed -i '/jcenter()/d' ./platforms/android/build.gradle
#append jcenter
sed -i '/maven {/{
N
N
a\
 jcenter()
}' ./platforms/android/build.gradle
cat ./platforms/android/build.gradle

Reference the script in the android platform node in config.xml using the hook reference shown below.

<platform name="android">
    <hook src="maven_swap.sh" type="before_build" />
    ...
</platform>

Add execute permissions using chmod +x maven_swap.sh. If your OS doesn't include the chmod command execute permissions can be added using git. See the following article for more details.
