There is no “Launch agent via Java Web Start” option in my jenkins when I adding a windows slave node

Question

I have already configured the java enviroment and installtion path

Answer 1

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...

1. Login to Jenkins as admin
2. Manage Jenkins > Configure Global Security > TCP port for JNLP agents

Do yourself a favor and pick a static port assignment...

Answer 2

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.

Answer 3

I had similar issue after updating my Jenkins, I then used "Launch agent by connecting it to the master" method to launch and my port "TCP port for inbound agents" under - Manage Jenkins => Configure Global Security => Agents => TCP port for inbound agents got changed to 8888. I have updated it back to 50000 and that resolved the issue. Hope it helps.

Answer 4

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
