The Problem I’m facing

I’ve try to migrate an other configuration to new jenkins
after migration , if i delete the configration. Jenkins instance won’t be able to restart becasue of io.FileNotFound Exception .

What I can do is recover the configuration file , and restart jenkins again. then execute code below:

import io.jenkins.plugins.casc.CasCGlobalConfig
CasCGlobalConfig config = GlobalConfiguration.all().get(CasCGlobalConfig.class)
config.setConfigurationPath(null)
config.save()

I can not image what happend if I lost my configuration.

Feature Request

1. able to delete & update Configuration Source
2. Jenkins can start normally even if Configuration Source is missing .

The config file that you should be deleting is io.jenkins.plugins.casc.CasCGlobalConfig.xml and should be located at $JENKINS_HOME
