David Handermann commented on NIFI-12213:
-----------------------------------------
Thanks [~mosermw], the pull request looks good and I will plan on merging
pending successful builds.
The {{nifi-standard-services-api-nar}} bundles {{{}nifi-utils{}}}, so most
modules had it in the class path at runtime, but a few don't as you found.
Those two modules were an oversight on my part with the restructuring. Some
modules had direct dependencies on nifi-utils, others had transitive
dependencies. The transitive dependencies worked when nifi-utils had the
default {{compile}} scope, but with the addition of the {{{}nifi-bom{}}}, it is
now necessary to declare {{nifi-utils}} explicitly. This should be better going
forward, as it surfaces direct dependencies versus relying on implicit
relationships.
Thanks again for the quick turnaround!
