Hello, I am trying to upgrade the elasticsearch for java from 7.6.2 to 7.16.15, but the following classes seem to be deprecated:
.......Producer.java:15: error: cannot find symbol
import org.elasticsearch.client.RestClient;
^
symbol: class RestClient
location: package org.elasticsearch.client
.......Producer.java:16: error: cannot find symbol
import org.elasticsearch.client.RestClientBuilder;
^
symbol: class RestClientBuilder
location: package org.elasticsearch.client
.......Producer.java:17: error: cannot find symbol
import org.elasticsearch.client.RestHighLevelClient;
^
symbol: class RestHighLevelClient
location: package org.elasticsearch.client
.......Producer.java:48: error: cannot find symbol
import org.elasticsearch.common.unit.TimeValue;
^
symbol: class TimeValue
location: package org.elasticsearch.common.unit
.......Producer.java:51: error: cannot find symbol
import org.elasticsearch.client.RestClient;
Is there a changelog or a guide mentioning the packages for these classes?
