Ionic - Could not resolve com.android.tools.build:gradle:3.3 - ionic2

Question

I'm trying to build my Ionic project and deploy it to my device, however every time I do I'm getting the following error message
`
A problem occurred configuring root project 'android'.
Could not resolve all dependencies for configuration ':classpath'.
Could not resolve com.android.tools.build:gradle:3.3.

I can confirm that I've installed Gradle and that it's on the PATH
gradle -v
Gradle 3.3
Build time: 2017-01-03 15:31:04 UTC
Revision: 075893a3d0798c0c1f322899b41ceca82e4e134b
Groovy: 2.4.7
Ant: Apache Ant(TM) version 1.9.6 compiled on June 29 2015
JVM: 1.8.0_131 (Oracle Corporation 25.131-b11)
OS: Windows 10 10.0 amd64
And I have the following in build.gradle file
buildscript {
repositories {
mavenCentral()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.3'
}
allprojects {
repositories {
mavenCentral();
jcenter()
}
}
But it still fails to build - any ideas here? I've also tried changing the mavenCentral() function to a maven = { url: 'http://maven.google.com' } object, but that doesn't work neither.
