So the issue was in fact that not all the Pipeline Plugin suite was installed... curiously, I thought that the 2.73 RPM package would have included all of Pipeline plugins ? Like workflow-job, etc.. But the RPM package does not.
*My suggestion to the Dev team* is to get the full Pipeline Plugin suite into the RPM's going forward. That will alleviate a lot of headache I think for most folks doing standard CI/CD since many have already converted to Pipeline for that, such as us at Ericsson. After I installed the Pipeline Plugin suite, than the error went away since it now understood <flow-definition> class since the workflow-job plugin was available again.
