Recently, I found few methods not found in the 6.2.1 version of High-Level-Rest-Client and these methods exists in 6.3.0 version, but I don't depend on this version with maven tool.

You can try the SNAPSHOT version. See [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/6.x/java-rest-high-getting-started-maven.html#java-rest-high-getting-started-maven](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/6.x/java-rest-high-getting-started-maven.html#java-rest-high-getting-started-maven)

I want to use Indices Exists API and Exist Alias API in my application and I found these API are only in 6.3.0 version not in other version.
I want to know how I can do to Implement these API with 6.2.0 version.
Thanks
