Elasticsearch Java Client known issues

We handle all of our issues in our Github repo.

8.16.7 is the first patch released without a matching rest-client version, so the elasticsearch-rest-client dependency is missing, causing the following exception:

Could not resolve dependencies for project
[ERROR] dependency: org.elasticsearch.client:elasticsearch-rest-client:jar:8.16.7 (compile)
[ERROR] 	Could not find artifact org.elasticsearch.client:elasticsearch-rest-client:jar:8.16.7 in central (https://repo.maven.apache.org/maven2)

To use this version of the client, set the latest available version explicitly in the project:

// gradle
implementation("org.elasticsearch.client:elasticsearch-rest-client:8.16.6")

<!--maven-->
<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>elasticsearch-rest-client</artifactId>
    <version>8.16.6</version>
</dependency>

The latest major version of the client doesn't depend on elasticsearch-rest-client anymore, as the new built in Rest5Client is available, but it does depend on the Apache commons-logging dependency, which is missing, causing the following exception:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
	at co.elastic.clients.transport.rest5_client.low_level.Rest5Client.<clinit>(Rest5Client.java:115)
	at co.elastic.clients.transport.rest5_client.Rest5ClientTransport.buildRest5Client(Rest5ClientTransport.java:65)
	at co.elastic.clients.transport.rest5_client.Rest5ClientTransport.<init>(Rest5ClientTransport.java:42)
	at co.elastic.clients.transport.ElasticsearchTransportConfig$Default.buildTransport(ElasticsearchTransportConfig.java:110)
	at co.elastic.clients.elasticsearch.ElasticsearchClient.of(ElasticsearchClient.java:190)

To use the new Rest5Client, add the commons-logging dependency:

// gradle
implementation("commons-logging:commons-logging:1.3.5")

<!--maven-->
<dependency>
    <groupId>commons-logging</groupId>
    <artifactId>commons-logging</artifactId>
    <version>1.3.5</version>
</dependency>
