How to provide path in jenkins

Question

I have installed Jenkins through the wars file but now I have two JDK15 and JDK8 in the system...Can you please tell me how to run Jenkins with JDK8 as it is automatically taking JDK15 .

Answer 1

You can do that by setting up a Jenkins file where you can specify the java version for each job. You can find more information on https://www.jenkins.io/doc/book/pipeline/jenkinsfile/

Answer 2

you can try to switch Java version using this:

sudo update-java-alternatives --set [JDK/JRE name eg java-8-oracle]
