Spring Cloud Contract producer cannot send message

Question

I'm trying to incorporate Spring Cloud Contract into an existing project. I've had some success with REST but I'm struggling to set up the messaging side.

Thus far I've set up a contract on the producer, which does produce a test in target/generated-test-sources/contracts. I've also set up a base class for the test.

I can't get past this error:

2017-09-08 17:10:51.759 ERROR - --[]- [ main] o.s.c.c.v.m.stream.StreamStubMessages : Exception took place while trying to resolve the destination. Will assume the name [invites]

and later

My application.yml file under src/test/resources:

spring: cloud: stream: bindings: output: content-type: application/json destination: invites

I have the following dependencies:

`

I've combed through the docs, watched Marcin's talk and looked through the samples for Spring Cloud Contract but I'm stuck. Any help would be greatly appreciated.

Hi! Can you try to use the release train to manage dependencies? Also ensure that you have the @EnableBindings annotation. Also it would be great to see your sample published somewhere on github. It will be easier to help you. — Marcin Grzejszczak, Sep 09 '17 at 00:22
Hi Marcin. Using the release train has resolved the problem. Thank you! — James Swafford, Sep 11 '17 at 13:24
Cool, I've added my answer. Could you please mark it as the appropriate one? — Marcin Grzejszczak, Sep 11 '17 at 13:25
Sorry Marcin, I spoke too soon. I've created a demo project @ https://github.com/jswaff/scc-demo. I'm sure I'm missing something simple but I can't put my finger on it. Would you mind having a look? — James Swafford, Sep 11 '17 at 21:09

First issue:

Please use the release train. In the release train, we know that there are no invalid dependencies.

Second issue:

You don't have the @EnableBinding(Source.class) annotation. That's why Stream doesn't know how to bind to the output channel.

If you go to the Spring Cloud Contract samples you'll notice this line on the main application class (https://github.com/spring-cloud-samples/spring-cloud-contract-samples/blob/master/producer/src/main/java/com/example/ProducerApplication.java#L9). After I've added this line to your code, the context started but the tests failed cause the message wasn't sent.
