| To reproduce in 2.14-SNAPSHOT:
- start on a new home
- swat aside the setup wizard
- install github-branch-source including all dependencies
- manually upload workflow-scm-step-2.0.hpi (downgrading from the 2.2 installed from the UC)
- restart
You will see a warning about cyclic dependencies:
... hudson.PluginManager$1$3$2$3 reactOnCycle
SEVERE: found cycle in plugin dependencies: (root=Plugin:workflow-scm-step, deactivating all involved) Plugin:workflow-scm-step -> Plugin:git -> Plugin:workflow-scm-step
Which looks fine (you need to update workflow-scm-step to solve the conflict) until you realize it is disabling git but not its dependencies. So then you see a lot of extension loading errors, which would normally be just noise:

and at this point Jenkins startup ends; the UI just says Please wait while Jenkins is restarting... forever. These steps to reproduce are somewhat artificial. The original report comes from CloudBees Jenkins Enterprise: after starting 1.642.4.1 and installing subversion from the update center, Jenkins will not start (though in that case the fatal error comes a little later and lacks the "in a bad way" message. |
