It seems that you're facing
this again. But it's difficult to determine without more information. About my last request, I'm referring to the launch command output (not about any log).
When you launch Rundeck (`java -jar rundeck.war`) you will see that. That full stack is there for sure. If you're launching rundeck as a service make sure to redirect that output to a file like: `java -jar rundeck >> /path/to/service.log`) try to import and the full error stack will be there.
In that way, you can save in a log the essential Rundeck activity information.
Also, try to import the project without conserving the UUID and without SCM config.
Regards.
