We use the following project to streamline dependencies across our modules: http://git.magnolia-cms.com/projects/BUILD/repos/boms/browse
With the Maven plugin for freestyle jobs, building this repository would trigger downstream modules that import it in the following way: https://git.magnolia-cms.com/projects/PLATFORM/repos/ce.pub/browse/pom.xml#67
I don't believe this has been implemented as I don't see that scope in the Dependencies Fingerprint Publisher. The Maven dashboard for that job lists no upstream nor downstream dependencies either.
I'm not sure of the differences between this plugin vs. the one that works on freestyle jobs. Could this feature be implemented?
