Any update on reloading the job configuration when the jobs are inside a folder?  Reloading will not load "config.xml" changes for jobs that exist in a folder.

Using:  Jenkins ver. 1.642.4.1 (CloudBees Jenkins Enterprise 15.11)

Issue still present: core version 2.190.2

Folder plugin: org.jenkins-ci.plugins:cloudbees-folder:6.9

Just created a whole load of jobs in a Folder.
Did a mass change inside the config files manually ( using a script )
Reloaded config ManageJenkins->reload configuration from disc

Jenkins updated, jobs inside folders were not updated
I'll go for the above...
*Jenkins Version 2.219 *
( tried it on an earlier version, thought I had done something wrong, only a few jobs so changed using Jenkins GUI .. and ignored it.)
All latest plugins installed

Raised it to Major
I have many jobs in folders and changing e.g. the clearcase branch in 20+ jobs using the Jenkins GUI is not amusing when a perl one liner does it almost instantly.

got caught by this again - now I have more folders and jobs.
A one line perl changes all config.xml files, expected a reload config from disk to work.
Jenkins is constantly running jobs, a new restart is not possible.
A reload config allows the jobs to continue.
( does not - my mistake, no downstream job were started, really blown my CI system )
Does raising it to critical put more emphasis on this defect ?
using Jenkins LTS 2.235.5
all plugins are up to date.

Hi, I faced same issue. I need to update job and folders config.xml files manually and then get changes reflected in Jenkins. jenkins-cli reload-configuration was not working for jobs under folders. and "Reload Configuration from Disk" (in UI) was also not working.

TEMP SOLUTION (which worked for me):

create file: reload-configuration.groovy with content

_{import jenkins.model.Jenkins;}

_{import hudson.model.AbstractItem;}

_{import java.io.InputStream;
import java.io.FileInputStream
import java.io.File;
import javax.xml.transform.stream.StreamSource;}

_{Jenkins.instance.getAllItems(AbstractItem.class).each{job ->
  def configXMLFile = job.getConfigFile();
  def file = configXMLFile.getFile();}

  _{if (file.exists()) {}

    _{InputStream is = new FileInputStream(file);}

    _{job.updateByXml(new StreamSource(is));
    job.save();}

    _{println("Config reloaded: " + job.fullName);
  }
}}

And then run it with (add your auth method if needed): 

_{java -jar jenkins-cli.jar -s https://${JENKINS_ADDRESS}/ groovy = < reload-configuration.groovy}

This script goes through all items (jobs/folders) and updates their configs.

Please let me know if something is not clear in this explanation.
