hello, i have an aggregation pom named all-modules-pom.xml and it has a build section with pact broker info but when i run mvn pact:publish -f all-modules-pom.xml i got error. Can you advise a solution?

I don't know Maven that well, but it looks like it is not finding the Pact plugin. Can you try adding it to your project POM?

you are right, this is maven issue indeed. It works if I invoke the goal like this: au.com.dius.pact.providermaven4.1.17:publish
