java.lang.NoClassDefFoundError: com.amazonaws.services.s3.AmazonS3

When trying to make Spring Cloud Contract work with 4.0.8 version of Pact JVM Consumer, I get the following exception

Caused by: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

When checking the dependencies I can see that I have a dependency on AmazonS3.

Of course I don't use AmazonS3 at all. Can you mark this as optional or maybe I'm doing something wrong?

[marcingrzejszczak]

As a workaround I need to explicitly pass the AWS dependency.

It shouldn't be loading that class if you are not using Amazon S3 as a source of pact files.
