I'm trying to publish pact using the maven plugin available. Reading these docs: https://docs.pact.io/implementation_guides/jvm/provider/maven#configured-as-jvm-system-properties But im unable to set the consumer version. Ive tried

mvn pact:publish -Dpact.publish.consumer.version=0.2-SNAPSHOT
export PACT_PUBLISH_CONSUMER_VERSION=0.2-SNAPSHOT

Neither seem to work. Im getting the following error from the plugin when running

mvn pact:publish

Cannot change the content of the pact for Producer version 0.1-SNAPSHOT and provider Producer, as race conditions will cause unreliable results for can-i-deploy. Each pact must be published with a unique consumer version number

Can anyone tell me how i can increment the consumer version of the pact?

Can you provide debug logs?

the issue is that you are publishing a contract over an existing consumer version

@Matt (pactflow.io / pact-js / pact-go) thanks for the explanation. Just so I understand you are saying the reason im seeing this error is because there has been no change on the contract between

0.1-SNAPSHOT

and

0.2-SNAPSHOT

?

I didn’t properly read your message, sorry Ben. Your question was how to bump the version, which I don’t know how to answer I’m afraid. According to this that key looks correct, assuming

-D

sets the system property as expected. The env var looks wrong though (and is exported after the publish command so would have no effect) it should be

PACT_PUBLISH_CONSUMER_VERSION

it seems

@Matt (pactflow.io / pact-js / pact-go) No worries thanks for looking into it though. After a little more reading it looks like I can do what i want via the pact_broker-cli so im going to go that route I think

I generally would recommend the CLI also (we also have a docker image and standalone version of that. Search the docs for a link)
