service registration example is not working

[simon1212]

It looks like consul client 0.14.0 is using the wrong version of jackson-datatype-guava.

When i execute

    @Test
    public void testServiceRegistration() throws Exception {

        final Consul consul = Consul.builder().build(); // connect to Consul on localhost
        final AgentClient agentClient = consul.agentClient();

        final String serviceName = "MyService";
        final String serviceId = "1";

        agentClient.register(8080, 3L, serviceName, serviceId);
    }

I get the following exception:

java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.type.ReferenceType.upgradeFrom(Lcom/fasterxml/jackson/databind/JavaType;Lcom/fasterxml/jackson/databind/JavaType;)Lcom/fasterxml/jackson/databind/type/ReferenceType;

This solved the problem for me:

Since you already fixed it, how about a pull request.

[rickfast]

Unit tests are passing, and they perform registrations. Are you sure there's not a conflict with your other dependencies

[simon1212]

pretty sure there where no other dependencies on this. i'm trying to reproduce the problem in the consul-client repo.

[simon1212]

ok there is a dependency conflict in my project. sorry for wasting your time. thanks for the fast response!

[rickfast]

No problem
