Jenkins won't install recommended plugins on Windows

Question

I'm trying to run Jenkins on my Windows laptop using their .war package. The Java version I have installed is jdk-11.0.12, and as far as I saw, Java 11 is supported by Jenkins.

After running the java -jar jenkins.war command, everything works fine (connecting to localhost:8080 and entering the initialAdminPassword).

The problem comes when deciding what plugins to install. I clicked on the option that lets Jenkins automatically install the recommended plugins for me, but, unfortunately, all of these plugins seem to fail installing:

This is a part of my log:

Does anyone have an idea what the problem can be? Any help would be appreciated.

Answer 1

I had the very same problem: I tried to import into java keychain all jenkins certificates but no luck. I had java JDK11.0.1

I solved by installing JRE8, the jre1.8.0_331 to be precise.

You then have to change C:\Program Files\Jenkins\jenkins.xml for pointing to jre8 and also firewall exception named jenkins: firewall > advanced settings > Inbound rules > jenkins > right click: properties > Programs and Services.
