Here's what I did: yum update jenkins
Here's what's happening trying to get version info after upgrade. Also won't start with systemctl start jenkins. [root@nd645bd001 ~]# /bin/jenkins -version Sep 14, 2022 10:56:24 AM executable.Main verifyJavaVersion SEVERE: Running with Java class version 52, which is older than the Minimum required version 55. See https://jenkins.io/redirect/java-support/ java.lang.UnsupportedClassVersionError: 52.0 at executable.Main.verifyJavaVersion(Main.java:145) at executable.Main.main(Main.java:109) Jenkins requires Java versions [17, 11] but you are running with Java 1.8 from /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.342.b07-1.el7_9.x86_64/jre java.lang.UnsupportedClassVersionError: 52.0 at executable.Main.verifyJavaVersion(Main.java:145) at executable.Main.main(Main.java:109) Seems I need to upgrade java, but jenkins doesn't control java. Please advise. Should I just yum update java? Thanks, Eric -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
