Trigger a build when a change is pushed to GitHub
Enable Java web start option
The option to “Launch slave agents via Java Web Start” is missing from new node configuration, how can I add it to the options menu?
Sometimes, it will be visible automatically and sometimes we need to enable it with below setting.
Enable the TCP port of JNLP agents to enable this option for slaves.
Manage Jenkins > Configure Global Security > TCP port for JNLP agents
Set it to either Fixed (for this option also set the port number) or Random.

Below video I have created using these links.
My Repository link contains some sample exported plugins text file and the windows tool.
