Set consumer version from gradle CLI

[jasondamour]

Hello,

Maybe I am misunderstanding something. In the pact foundation docs, one of the recommendations is to version the published pacts from the consumer with unique versions (https://docs.pact.io/getting_started/versioning_in_the_pact_broker#rules).

However, the gradle plugin does not have any documented support for setting consumer version via CLI, like project or system property. So how can I pass git commit info into the plugin.

I cannot add the git info plugin to my projects.

Thank you.

It is documented here: https://github.com/pact-foundation/pact-jvm/tree/master/provider/gradle#including-the-consumer-branch-when-publishing-min-versions-41334219434

@rholshausen I tried this again, it doesn't seem to be working. Here is the full command our CI server is running:

./gradlew --info --stacktrace --console=auto --no-daemon 
pactVerify 
-Ppact.verifier.publishResults=true 
-Dpact.verifier.buildUrl=https://gitlab.[masked]/-/pipelines/626854602 
-Dpact.provider.branch=[masked] 
pactTests 
pactPublish 
-Dpact.publish.consumer.buildUrl=https://gitlab.[masked]/-/pipelines/626854602 
-Dpact.publish.consumer.branchName=[masked] 
-Dpact.publish.consumer.version=c3982fce0f665f4116ef9ab788efb720ea302b88

And here is the error:

> Task :pactPublish FAILED
Publishing 'CONSUMER-PROVIDER.json' ... 
FAILED! 409 Conflict - 
{"error":"Cannot change the content of the pact for CONSUMER version

It seems to take the version from gradle.properties regardless of system property

[rholshausen]

What version of Pact-JVM Gradle plugin are you using?

[rholshausen]

Actually, looks like a bug. If the consumerVersion property is not set, it will set it to the version from the build, and then won't get the value from the system property because it is set to the version from the build.

[rholshausen]

You can work around this by setting the consumerVersion property in the publish block in your gradle build. I.e. something like

pact {
    publish {
      consumerVersion = System.getProperty('pact.publish.consumer.version')
    }
}

Thanks @rholshausen for looking into this.
