We have multiple customers who are using Maven instead of Gradle, which means that adopting Realm Kotlin is a challenge.

To make onboarding easier we should finish this sample: https://github.com/realm/realm-kotlin-samples/pull/42

It should demonstrate the following:

• How to structure a project that contains both Maven and Gradle. In a way so Maven can consume code from the Gradle project.
• How to create a Repository interface that makes consuming Realm Kotlin easier when the Maven project is written in Java.
• How to publish artifacts from Gradle, either locally during the build process, to MavenLocal or a custom Nexus
