I'm using the JAVA API. I tried the following:

```
org.elasticsearch.node.Node node = nodeBuilder().node();
Client client = node.client();

```

and then the following:

```
Client client = TransportClient.builder().build() 
 .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9200));

```

But they both gave me the following error:

```
Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/ImmutableMap

```

I am using Elasticsearch 2.0.0 and it is running on port `9200`

Help please? What is causing that error and how can I fix it?

Missing dependencies probably

I'm using a Java application project in netbeans. Are you talking about this dependency?

```
<dependency>
   <groupId>org.elasticsearch</groupId>
   <artifactId>elasticsearch</artifactId>
   <version>${es.version}</version>
</dependency>

```

Where can I add this? I do not have a pom.xml file.

I think it's best to consult the netbeans community then.

This reads like one of the few transitive dependencies Elasticsearch has is missing: [GitHub - google/guava: Google core libraries for Java](https://code.google.com/p/guava-libraries/) is the project that has the class.

Hope this helps,
