安装了KDE Neon Dev Stable Edition（基于Ubuntu 16.04LTS），安装了openjdk 8和Jenkins 2.83（LTS）。安装程序一直运行，直到安装程序尝试启动jenkins（systemctl start jenkins）
那时我收到了这个错误
Feb 08 10:29:23 UX31A jenkins[13911]: ...fail!
Feb 08 10:29:23 UX31A systemd[1]: jenkins.service: Control process exited, code=exited status=7

试图查看它是否可以找到java，它确实也尝试添加配置，java的路径以便不存在冲突，但错误仍然存在。
有人有这个问题吗？
谢谢！
EDIT systemctl status jenkins.service
