What dependency is missing when I get java.lang.NoClassDefFoundError: javax/ws/rs/client/RxInvokerProvider error?

Question

I have a small project where for testing purposes I execute my jersey 2 client by unit test. But, unfortunately, I got the error attached. I don't know what dependency still missing. At the moment Jersey's webpage is down due to maintenance.

I put the same Relevant part of pom.xml, test code and tested code also attached.

public void getWorkItems() {
        ClientConfig clientConfig = new ClientConfig();
        clientConfig.property(ClientProperties.READ_TIMEOUT, 2000);
        Client client = ClientBuilder.newClient(clientConfig);    

        WebTarget webTarget = client.target("https://fabrikam.visualstudio.com/DefaultCollection/_apis/wit/workitems?ids=100,101&api-version=1.0");

        Invocation.Builder inBuilder = webTarget.request(MediaType.APPLICATION_JSON_TYPE);
        Response response = inBuilder.get();    
    }


public class WorkItemTests {

    @Test
    public void Vsts_Test() {
        WorkItems workItems = new WorkItems();
        workItems.getWorkItems();
    }        
}
