How to declare 4.1.0-RC1 release of spring-data-elasticsearch - elasticsearch

Question

How to declare 4.1.0-RC1 release of spring-data-elasticsearch
https://github.com/spring-projects/spring-data-elasticsearch/releases
I used the following repositories, but it doesn't seem to work
implementation group: 'org.springframework.boot', name: 'spring-boot-starter-data-elasticsearch', version: '4.1.0-RC1'
maven { url "http://repo.spring.io/libs-release" }
maven { url "http://repo.spring.io/libs-milestone" }
maven { url "http://repo.spring.io/libs-snapshot" }
* What went wrong:
Execution failed for task ':compileJava'.
> Could not resolve all files for configuration ':compileClasspath'.
> Could not resolve org.springframework.boot:spring-boot-starter-data-elasticsearch:4.1.0-RC1.

You need to pull in Spring Data Elasticsearch in version 4.1.0-RC1, not the boot starter:
implementation group: 'org.springframework.data', name: 'spring-data-elasticsearch', version: '4.1.0-RC1'
It might be that you have to pull in a RC version of Spring Data Commons as well:
implementation group: 'org.springframework.data', name: 'spring-data-commons', version: '2.4.0-RC1'
