Expected a PactSource, but got ...

[darccide]

Hello, I am trying to walk through this tutorial. However, when I try to verify a pact (./gradlew ...:pactVerify) I get an error and the following message: Expected a PactSource, but got /Users/mycomputer/Documents/pact-workshop-jvm/providers/springboot-provider/build/pacts/Our Little Consumer-Our Provider.json

I am assuming that there is an issue with accessing the actual Pact, but not entirely sure how to remedy it. The Pact has been created and exists in the above file path.

Thanks!

I am running into the same issue in step4

Expected a PactSource, but got /Users/mycomputer/github/pact-workshop-jvm/providers/springboot-provider/build/pacts/OurLittleConsumer-OurProvider.json
Failed to load pact file
kotlin.KotlinNullPointerException

It looks like pact is a pretty good solution for contract testing.
I am looking forward to being unblocked and continue hands-on the exciting journey.

I haven't heard anything from Pact. I will repost here if I am ever able to get unblocked.

Hi folks, apologies it looks like we didn't have issue notifications setup for this.

Please note that this repo has been recently superceded by https://github.com/pact-foundation/pact-workshop-jvm-spring, which is more aligned to our other workshops. I'll update our main docs to reflect this (docs.pact.io and in the README here).

But, the issue remains. I'm not sure what the specific issue is with this workshop (@uglyog any ideas?)

This is the truncated stacktrace from step 4:

I was able to get it to pass as follows

      hasPactsWith('Our Little Consumer') {
        pactFileLocation = file("$buildDir/pacts/")
      }

Does that indicate a bug with the pactSource property?

I raised an issue on the Pact-JVM repo to address this
