How to change the JDK for a Jenkins job?

I have imported the jenkins jobs from existing jenkins server from another machine. But the problem is, it has the JDK referenced as per the old machines and I want to change it to use the JDK configured in my new jenkins. But I am unable to find any way of doing this. So, please if you have come across this situation and found a way then please help me too.

Thanks.

Answer

There is a JDK dropdown in “job name” -> Configure in Jenkins web ui. It will list all JDKs available in Jenkins configuration.

As per @Derek comment below, n newer versions, you can find it in Manage Jenkins -> Global Tool Configuration -> JDK.

Note that you need the “Overall/Administer” permission to manage Jenkins.
