Jenkins refuses to start - unknown argument --ajp13Port=-1

Question

My jenkins installation on Debian was upgraded (using apt) - and now jenkins refuses to start. I can see the following in the log:

Exception in thread "main" java.lang.IllegalArgumentException:
     Unrecognized option: --ajp13Port=-1

My jenkins version is 2.381. Unfortunately, I now don't know which version was installed prior to this, but it definitely worked and no config changes have been made.

How can I get it to start?

I found the solution. File /etc/systemd/system/jenkins.service.d/override.conf contained the following line:

Environment="JENKINS_OPTS=  --ajp13Port=-1"

I commented this line - and the service started without an issue.

Looks like the upgrade process (via apt) doesn't deal with the configuration overrides correctly.

It does. overrides are supposed to NOT be touched by apt. – Gerald Schneider Dec 08 '22 at 14:21

Had the same message on Ubuntu 20.04.1 and Jenkins 2.375.1. It almost looks like the parameter isn't supported anymore. Removed it from /etc/default/jenkins and it started again.

I hope `Ubuntu 9.4.0` is a typo. – Gerald Schneider Dec 12 '22 at 08:24
