ISSUE:

Installed Jenkins version 2.492.3 manually via rpm (jenkins-2.492.3-1.1.noarch.rpm) in RHEL 9.5 server.
While trying to start jenkins service (systemctl start jenkins), it gets timedout with below error.
Job for jenkins.service failed because a timeout was exceeded.
See “systemctl status jenkins.service” and “journalctl -xeu jenkins.service” for details.
Jenkins URL in browser is stuck indefinitely saying “Jenkins is getting ready to work” and hence unable to access Jenkins UI.
Below are captured from jenkins.log file for reference

Startup timeout parameter set is #TimeoutStartSec=90 in service file.
I tried with changin jenkins home directory, renaming plugins folder to see if any corrupted files with plugins, changing setenforce in server between “permissive/enforcing” but no luck.
I am looking for the reason for this error and ways to resolve this?

It looks like Jenkins is having trouble starting because it can’t find a key Groovy class:
java.lang.ClassNotFoundException: groovy.lang.ExpandoMetaClassCreationHandle

This usually points to a problem with the Groovy libraries Jenkins depends on, possibly something missing or corrupted in your installation.

What Might Be Happening

Jenkins needs certain Groovy JAR files at startup, and if they’re missing (or incomplete), you’ll often see errors like this. Something likely went wrong with the installation, or maybe the cache is in a weird state.

A Few Things You Could Try

1. Double-check the Groovy libraries
You might want to take a quick look inside the Jenkins installation to see if the Groovy JARs are there:

Common paths include /usr/lib/jenkins/jenkins.war or /var/cache/jenkins/war/WEB-INF/lib
Look for files like groovy-*.jar
If they’re missing or suspiciously small, that could be the issue.

2. Try a fresh reinstall of Jenkins
Sometimes it’s easier to just reinstall Jenkins to make sure everything is clean:

sudo systemctl stop jenkins
sudo yum remove jenkins
sudo wget -O /etc/yum.repos.d/jenkins.repo \
    https://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key
sudo yum upgrade
# Add required dependencies for the jenkins package
sudo yum install fontconfig java-21-openjdk
sudo yum install jenkins

3. Clear Jenkins’ cached files
Even after reinstalling, old cached files can cause issues. It might help to delete the exploded war cache:

sudo rm -rf /var/cache/jenkins/war

4. Permissions check
It’s also worth checking that the Jenkins user has read access to everything under /usr/lib/jenkins and /var/cache/jenkins. Sometimes this can trip things up silently.

5. Start Jenkins again and watch the logs

sudo systemctl daemon-reload
sudo systemctl start jenkins
journalctl -u jenkins -f

In Short…

This kind of error usually clears up after reinstalling Jenkins and removing the cached war directory. If the problem sticks around, it might be worth double-checking for any custom plugins or scripts that could be affecting the classpath.
