The following libraries and services were upgraded to be built with Java 25 and Gradle 9 on Jenkins, to run on Java 25 and to use the latest versions of Spring Boot 3 (there applicable, of course):
Cosmic APIWeather APIStorage APIMath ParserSkos ParserMy Turnkey Jenkins LXC stopped updates via apt a month ago, so I had to update the key:
curl -fsSL https://pkg.jenkins.io/debian/jenkins.io-2026.key | sudo tee /usr/share/keyrings/jenkins-keyring.asc > /dev/null
And to update the repository:
echo "deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] https://pkg.jenkins.io/debian-stable binary/" | sudo tee /etc/apt/sources.list.d/jenkins.list
Also, Jenkins needs Java 21 or higher. Installing it via deb package (Zulu):
sudo dpkg -i zulu25.32.17-ca-jdk25.0.2-linux_amd64.deb
In case any dependencies are missing, install them:
sudo apt --fix-broken install -y
Finally, fix the jenkins service path:
nano /lib/systemd/system/jenkins.service
Change
ExecStart=/usr/bin/java -jar /usr/share/jenkins/jenkins.war`
to
ExecStart=/usr/bin/java -jar /usr/share/java/jenkins.war
Reload systemd:
sudo systemctl daemon-reload
Keycloak adapter and Spring Boot starter are replaced with Spring Security OAuth2 configuration, the steps taken are already in the documentation
Upgraded to Angular v20 using Nx migration tool and some manual fixes, according to the official migration guide.
Documentation is ready for the migration of the Jenkins build server to a dedicated location.
Documentation is ready for the migration of Clematis Money Tracker application to HTTPS and upgrade of the technological stack.
The embedded Keycloak project is decommissioned in favor of a standalone Proxmox virtual machine. The documentation is updated.
The Palantir Docker Plugin is now EOL, which probably is the old news, however, the worse part is that it is waiting to be updated for Gradle 8.12 and up: https://github.com/palantir/gradle-docker/issues/801.
Some Clematis APIs are dependent on the plugin, so looking for workarounds or removal.
