Provider pactVerify isn't picking up JSON Pact file

Question

I have two projects in the same repo, with completely separate directory structures (consumer in /test-consumer, provider in /app).

The consumer check outputs a JSON Pact file in /test-consumer/build/pacts, as expected by

dependencies { test { systemProperties['pact.rootDir'] = "$buildDir/pacts" } }

I then copy the file into /app/build/pacts/, and put this same systemProperties line into my provider's build.gradle.

The sample project that I'm plagiarising from is using a Pact broker, so I guessed I can take that out, and replace it with the rootDir, but it's not working. This is what I get:

WARNING: There are no consumers to verify for provider 'Coffee Ordering Provider'

So, it seems like it's finding the Pact files, but can't find a provider+consumer pair in any of them.

TL;DR: What am I doing wrong?

Here are some code bits to help:

dependencies {
  ...
  test { systemProperties['pact.rootDir'] = "$buildDir/pacts" }
}

pact {
  serviceProviders {
    'Coffee Ordering Provider' {
      port = 8080

      startProviderTask = startProvider
      terminateProviderTask = stopProvider
      stateChangeUrl = url('http://localhost:8080/pactStateChange')
    }
  }
}

You are getting that warning because you have not told the pact plugin where to find the pact files. For pacts in a directory, add the following:

pact {
  serviceProviders {
    'Coffee Ordering Provider' {
      port = 8080

      startProviderTask = startProvider
      terminateProviderTask = stopProvider
      stateChangeUrl = url('http://localhost:8080/pactStateChange')

      hasPactsWith('Coffee Ordering Consumers') {

          // Will define a consumer for each pact file in the directory.
          // Consumer name is read from contents of pact file
          pactFileLocation = file("$buildDir/pacts")

      }
    }
  }
}

Just a note that you were setting the pact.rootDir for all tests, but the pact verification does not run as a test.
