There is a [stack overflow answer](https://stackoverflow.com/questions/34110426/does-java-support-lets-encrypt-certificates) that will tell you more about it. You can download the Jenkins war file with your web browser from the [Jenkins download page](https://www.jenkins.io/download/) instead of attempting to download from inside Jenkins itself. Upgrading in a single step from Jenkins 2.195 to Jenkins 2.414.2 may bring many surprises, since you’re upgrading across multiple years of Jenkins versions and major Java versions. ---

Thank you. Just curious how do i find what java jenkins is using. I actually uninstalled all the JAVA that i had previously installed and Jenkins still runs. i found a jvm.dll under the Jenkins folder and suspect it is using it but how could i verify that or change Jenkins to use the newly installed one. and as for updated the current Jenkins to the latest Jenkins i have no problem with installing new and starting fresh. But when i tested this before i couldn’t get the current jobs imported to the new Jenkins installation. These jobs are not complicated jobs but when i tried to setup a job on new version i couldn’t get it working. email kept failing and i was not able to dig deep enough into finding out how it was email on the old version. ---

> [@hicpics](#): > > Just curious how do i find what java jenkins is using The “Manage Jenkins” → “System Information” page will usually show the Java version that is running. ---

Cool and yes it is configured to use the JVE folder installed under jenkins. What configuration file controls that in Jenkins. i don’t see any option for changing it so there must be a config/xml file that controls that.
