Spring-Hateoas Client using Traverson - client

Question

I want to consume my rest-service by Spring-Hateoas by Traverson, but I come to the following issue I didn't find anything in web.
I am using Spring-Boot 1.1.10.RELEASE.
My Client Call looks like follows:
...
final Traverson traverson = new Traverson(new URI("http://localhost:8080/bbsng-app-rest"), MediaTypes.HAL_JSON);
...
And I get following Issue:
java.lang.NoClassDefFoundError: Could not initialize class org.springframework.hateoas.client.Traverson

Ah, it seems Spring-Hateoas needs additional dependency Json-Path.
So following dependency will be expected:
<dependency>
<groupId>com.jayway.jsonpath</groupId>
<artifactId>json-path</artifactId>
</dependency>
