After the package has been installed, check default Java set on your Arch Linux machine. Install Java 17.

sudo pacman -S  vim jre17-openjdk

If you have java-7-openjdk set as default, Jenkins service will fail to start:

$ archlinux-java status 
Available Java environments:
  java-11-openjdk (default)
  java-17-openjdk

Set installed Java as default.

sudo archlinux-java set  java-17-openjdk

Check default version again to confirm:

$ archlinux-java get
java-17-openjdk

$ archlinux-java status
Available Java environments:
  java-11-openjdk
  java-17-openjdk (default)

Update JAVA path:

$ sudo vim /etc/conf.d/jenkins
JAVA=/usr/lib/jvm/default/bin/java

Start Jenkins application:

sudo systemctl daemon-reload
sudo systemctl restart jenkins
sudo systemctl enable jenkins

Check application status to confirm that it is running:

$ systemctl status jenkins
