I have follow the links and they own by root but with 777 permissions so enable for everyone to follow the link, the real file is read for everyone.. so not sure why is this happening.

Answer

Do you run Jenkins manually or via service?

It’s not recommended to run it manually via java -jar /usr/share/jenkins/jenkins.war but with service jenkins start|stop.

When you manually start, it’ll change owner to user which started jenkins.war via java, service runs under user:group jenkins:jenkins.

Default path for service Jenkins (Debian/Ubuntu) should be /var/lib/jenkins/jobs/<ProjectName>/workspace and everything inside /var/lib/jenkins/ must be owned by user jenkins and group jenkins:

chown -R jenkins:jenkins /var/lib/jenkins/

Also check if you have a properly installed and configured JDK inside your Jenkins project.
