Access Elastic Search Using Its Java Api's

I am trying to follow the Documentation of Elastic Search to get and post data from it using its java Api's. But i am constantly getting error.

This is the code i have tried as of now.

Settings settings = Settings.builder().put("twitter", "tweet").build();
TransportClient client = new PreBuiltTransportClient(settings)
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host1"), 9300))
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host2"), 9300));

GetResponse response = client.prepareGet("twitter", "tweet", "1").get();

The stack trace

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/ImmutableSortedMap at com.c1x.entity.Test.main(Test.java:20) Caused by: java.lang.ClassNotFoundException: com.google.common.collect.ImmutableSortedMap at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:335) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 1 more

You miss the google-collections.jar in your classpath. Add it and the error will go away.

If you are using maven as dependency Management tool, add the follwing lines to your pom.xml:

<dependency>
    <groupId>com.google.collections</groupId>
    <artifactId>google-collections</artifactId>
    <version>1.0</version>
</dependency>

Next jar is missing add lucene-core-<version>.jar

maven dependency is:

<dependency>
    <groupId>org.apache.lucene</groupId>
    <artifactId>lucene-core</artifactId>
    <version>6.5.1</version>
</dependency>
