Using elasticsearch Java API

Question

I am very new to elasticsearch. I found some simple java code for using elasticsearch:

import static org.elasticsearch.node.NodeBuilder.*;

// on startup

Node node = nodeBuilder().node();
Client client = node.client();

// on shutdown

node.close();

I am getting the following error:

package org.elasticsearch.node doesn't exist

Later, I found that I have put some information in pom.xml. What is that? How to make this simple program run?

Do you know what Maven is?

I mean that if you are using Maven, then you need to add elasticsearch-VERSION.jar as a dependency in your pom.xml.

If not, then you need to add elasticsearch jar in your project classpath and some other libs such as (it depends of elasticsearch version you are using):

antlr-runtime-3.5.jar
asm-4.1.jar
asm-commons-4.1.jar
jna-3.3.0.jar
jts-1.12.jar
log4j-1.2.17.jar
lucene-analyzers-common-4.6.0.jar
lucene-codecs-4.6.0.jar
lucene-core-4.6.0.jar
lucene-expressions-4.6.0.jar
lucene-grouping-4.6.0.jar
lucene-highlighter-4.6.0.jar
lucene-join-4.6.0.jar
lucene-memory-4.6.0.jar
lucene-misc-4.6.0.jar
lucene-queries-4.6.0.jar
lucene-queryparser-4.6.0.jar
lucene-sandbox-4.6.0.jar
lucene-spatial-4.6.0.jar
lucene-suggest-4.6.0.jar
spatial4j-0.3.jar

I'd recommend to use Maven because it's much easier to deal with dependencies.

Hope this helps
