IndicesClient.exists() can not be resolved

[philboeselager]

Elasticsearch version (bin/elasticsearch --version): 6.2.1

Plugins installed: []

JVM version : 1.8.0_111 (build 1.8.0_111-b14)

OS version : Linux 4.4.0-112-generic #135-Ubuntu x86_64 x86_64 x86_64 GNU/Linux

Description of the problem including expected versus actual behavior:

Following the official documentation , there should be a method exists(GetIndexRequest) .

But actually, there's no such method to be found in javadoc, sources, and therefore, the method can not be resolved.

Steps to reproduce:

1. use dependency "org.elasticsearch.client" % "elasticsearch-rest-high-level-client" % "6.2.1"

2. code:

   final RestClientBuilder builder = RestClient.builder(new HttpHost("localhost", "9200", "http"));
   final RestHighLevelClient client = new RestHighLevelClient(builder);
   final GetIndexRequest request = new GetIndexRequest().indices("myindex");
   assert(client.indices().exists(request));

3. compile

Provide logs (if relevant):

Error message is:

org.elasticsearch.action.admin.indices.get.GetIndexRequest cannot be converted to org.elasticsearch.action.get.GetRequest

Thanks for reporting this. The documentation link you've provided is for the next minor release as the version is 6.x. The docs you should be looking at are for the 6.2 version; there is a version selection drop down to switch between versions.

The indices exists API is a new edition that will be included in 6.3. #27384
