I build a project using mvn clean package and deployed on remote Ubuntu server using nohup java -jar app,jar. It works fine for a day or so, but then it shuts down. I read the nohup file, but it is still unclear why the app stopped.
Here is my pom.xml file:

I've already asked the same question on StackOverflow, but there is no answer.

To avoid wasting people's time, let's keep things in one place please. Closing in favour of the question on Stack Overflow.

closing, since the question duplicates https://stackoverflow.com/questions/71215504/jar-file-automatically-terminates-on-remote-ubuntu-server-after-a-day
