There is no "Launch agent via Java Web Start" option in my jenkins when I adding a windows slave node
This is a duplicate question from Server Fault: Answer Here
Java Web Start utilizes TCP so it has to be enabled and configured in Jenkins...
- Login to Jenkins as admin
- Manage Jenkins > Configure Global Security > TCP port for JNLP agents
Do yourself a favor and pick a static port assignment...
As of Jenkins version 2.176.3, there is option enabled when "Launch agent by connecting it to the master" which is same as "launch agent via java web start" once you enable the "Manage Jenkins => Configure Global Security => Agents => TCP port for inbound agents" as mentioned above.e.g. Fixed: 50000
Make sure that you've enabled a JNLP port in Manager Jenkins -> Configure Global Security. If no JNLP port is specified, then the JNLP slave option will not appear.
