Help for value to use additionalRemoteRepository URL config in Dependency Management for Interpreter Spark

I am stuck adding the following class to zeppelin:

https://mvnrepository.com/artifact/org.elasticsearch/elasticsearch-spark-20_2.10/7.5.2

What is the syntax for zeppelin.dep.additionalRemoteRepository to add mvnrepository.com here?

I also deployed a local version of apache archive, and tried https://archiva.secscs.com/repository/internal (where archiva.secscs.com is my local DNS name), but none worked.

Can you please give a hint what is the URL value I can put in the additionalRemoteRepository URL?

Thanks,
