Gradle build fails on Android - could not resolve all files for configuration

Hello guys,
I’m getting a build error when running the command ionic cordova run android --device. The error tells that a gradle resource could not be loaded, but I am able to get this resource in the browser on the same machine I’m working behind a proxy. I set the proxy in the gradle.properties file in my gradle home directory. Below is the console output.

ANDROID_HOME=C:\Users\dsimon\AppData\Local\Android\Sdk
