John Ament commented on JENKINS-33349

Re: Error after installing Pipeline/Workflow plugin I was able to fix it. 1. Manually remove the workflow packages from JENKINS_HOME/plugins 2. Upgrading all plugins. 3. Restarting jenkins. 4. Download the workflow plugins, and set to install on restart. 5. Then it was working fine.

Jesse Glick resolved as Cannot Reproduce

Generally a user error of some kind, though Jenkins currently makes it hard to diagnose. (Fixes in progress.)
