Google Cloud Storage backed Maven

A few more details:

Here is the jar in GCS that I would like to use as a dependency in a gradle project:

15

The build.gradle file for the project includes:

repositories {
	maven {
		url "gcs://rusa_api_poc/maven2"
    	}
	jcenter()
}

dependencies {
	compile group: 'rusaapi', name: 'Domain', version: '1.0'
}

But when I refresh the Gradle project, I get
Could not resolve: rusaapi:Domain:1.0

Any ideas?
