We have Jenkins setup with Multiple project(Folder). Each folder has 3 user groups: Developer, Lead, View. We need to restrict the nodes to projects, each project should be able to see only their specific node dedicated to their project
Example,
Project/Folder name – Atlassian
Groups assigned – Atlassian-Lead, Atlassian-Developer, Atlassian-View
Node – jenkins-atlassian
The members of these groups can only see thier Folder and also should see the only the node dedicated to their Project.

I have a Jenkins Jenkinsfile build job which generates a HTML report. This report is available as a build artefact and via the PublisHTML Jenkins plugin.

I have the EC2 plugin installed and configured on Jenkins. Workers are being successfully provisioned and connected to the controller.
Now the problem is that when trying to update properties of an already existing node / worker, the following exception is thrown:

i have big problems with jenkins in vps ubuntu

We just upversioned old Jenkins version from 2.319 to 2.426

According to the Email Extension and the example template html and text, I found the objects:

I’m starting to use the Parameter Separator plugin to separate the configuration parameters of a job that has many parameters.
The definition of the parameters is loaded from a configuration file. what is the syntax to separate parameters with a separator line?
I am trying this but the line is not showing

I try to create a plugin-based-app and I saw similar service on Jenkins. It allows to create plugins in .jpi/.hpi format and then upload/install this plugin. But I couldn’t figure its-pipeline out from source code.

The virtual machine used Jenkins very smoothly at the beginning, but one day suddenly the Jenkins page loaded very slowly. The page that could be loaded within 1 second before was often taken more than 10 seconds to load. But it is not the kind of stuck that cannot be loaded at all. All functions can be used normally, but the loading time is extremely long.
Use F12 of the browser to check the elements and find that there is an element called theme.css that often takes more than 10 seconds to load, and this element needs to be loaded every time a page is jumped.
Then I found theme.css hardcoded the IP which is when I installed the Jenkins and plugins. But my VM IP is dynamic. It will change after some time later.
Request IP is http://192.168.11.131, but my VM IP is http://192.168.11.137.
Hardcode
After forbiden the dark mode plugin and restart the Jenkins, I found the pages could be load in normal speed.

I have inherited management of some legacy Jenkins infrastructure and I am confused because I have two types of Gitlab API Tokens in my credentials:
