Try installing the language plugin as well: pip3 install cloudformation-cli-java-plugin --upgrade

[kmjewell]

That worked, thanks! Now the tests start running but are still failing. What endpoint should I be using if I want to test our contracts in prod?

I tried just using our prod service endpoint cfn test --endpoint https://ec2.us-east-1.amazon.com but got this error

E   botocore.exceptions.EndpointConnectionError: Could not connect to the endpoint URL: "https://ec2.us-east-1.amazon.com/2015-03-31/functions/TypeFunction/invocations"

[PatMyron]

shouldn't have to specify endpoint for cfn test

should just spin up SAM locally in your resource provider directory first: sam local start-lambda &

[kmjewell]

I was trying to avoid that due to all the extra setup & issues it involves. Is there a way to just run it against the prod service? Sounds like not?

So for using SAM locally, I ran into

Invoking software.amazon.ec2.networkinsightspath.HandlerWrapper::handleRequest (java8)

and was told I need to first run

mvn package

which then failed with

@kmjewell , I was able to reproduce following the tutorial here. I was able to fix the error by updating the Lombok version as suggested here.

Now I run into an error about an ambiguous method call injectCredentialsAndInvoke. After digging in, it looks like this this commit may have introduced the ambiguity: https://github.com/aws-cloudformation/cloudformation-cli-java-plugin/pull/338.
