Yes, this seems like a general chicken-and-egg problem when specifying parameter-config in the Jenkinsfile. It also affects any updated Jenkinsfile that adds a new parameter/changes a parameter , as these changes only take effect *after * the job is started. The only really working solution would be to run the Jenkinsfile twice (once for setup, e.g. parameters) and then to do the real work. But then what to do if the Jenkinsfile e.g. depends on a branch parameter? Which jenkinsfile should be used?
