I am attempting to upgrade to 2.0.0 but am having difficulty making 
ResourceExtension work for me.

I'm following the example that is in dropwizard-example and have this:

private static final ResourceExtension RESOURCE = ResourceExtension.builder()
    .addResource(new GamingResource(dao))
    .build();


What happens when that field is called in a test method (either way):

RESOURCE.client()target("/vg/all").request().get(List.class);

RESOURCE.target("/vg/all").request().get(List.class);


I receive a null pointer exception when the ResourceExtension attempts to call 
client() or target().


I know there are working unit tests for this class in the dropwizard-example 
project, so I am wondering if the cause of my problem is a dependency or pom 
issue.  Below is the pom.xml file I have.  I have attempted a number of 
variations based on the pom.xml in dropwizard-example.


All suggestions would be appreciated.
