following the steps to prepare a RC branch

I'm convinced this needs to change still:

CSDE-cordapp-template-kotlin/build.gradle

Lines 69 to 84 in 065d74c

	// R3 Internal repositories for dev
	// Repository provides Corda 5 binaries that implement Corda-API.
	// These will be made publicly available.
	// Final location to be decided.
	// Repository subject to change
	maven {
	url = "$artifactoryContextUrl/corda-os-maven"
	authentication {
	basic(BasicAuthentication)
	}
	credentials {
	username = findProperty('cordaArtifactoryUsername') ?: System.getenv('CORDA_ARTIFACTORY_USERNAME')
	password = findProperty('cordaArtifactoryPassword') ?: System.getenv('CORDA_ARTIFACTORY_PASSWORD')
	}
	}
	}

this looks like an internal dependence

The previous release PR looks very useful. #84
There are some internal references in gradle.properties and settings.gradle that can be removed as well
