Elasticsearch Java API Client

I want to run the following java code:

import java.util.Map;
import org.elasticsearch.action.get.GetResponse;
import org.elasticsearch.client.Client;
import org.elasticsearch.node.Node;
import static org.elasticsearch.node.NodeBuilder.*;

public class MongoDB {

public static void main(String[] args) {
    Node node = nodeBuilder().clusterName("elasticsearch").client(true).node();
    Client client = node.client();


    node.close();
}  
}

I've run the mongod with following command:

mongod --port 27017 --replSet rs0

Elasticsearch with default conf

And everytime I run my programm I get following error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/lucene/util/Version

NodeBuilder is no more in use as of latest ES (5.6.3).
Avoid using it, and start using TransportClient for future supports.

To use java client of elastic search.. You have 2 dependencies..
Elasticsearch jar and lucene core jar...

If you are making Osgi bundle you need to places names.txt file in bundle and specify config path in transport client settings.

Hope it helps...

Elasticsearch is a search server based on Lucene . you have to include lucene jar file lucene-core-x.x.x.jar and other dependent jar files to make this code working...
