Hi,  
I am trying to develop a spring boot based elasticsearch project and I am trying to use Java High Level Rest Client in the same.  
I am initializing the client like this:

> Caused by: java.lang.BootstrapMethodError: java.lang.NoClassDefFoundError: org/elasticsearch/common/CheckedConsumer

My pom.xml has the following dependencies:

> ```
> <dependency>
> <groupId>org.elasticsearch</groupId>
> <artifactId>elasticsearch</artifactId>
> <version>6.2.4</version>
> </dependency>
> <dependency>
> <groupId>org.elasticsearch.client</groupId>
> <artifactId>elasticsearch-rest-high-level-client</artifactId>
> <version>6.2.4</version>
> </dependency>
> 
> ```

Try add this:

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