How to deploy SpringBoot Maven application with Jenkins ?

I find very useful to first copy the artifacts to a specified area on the server to keep track of the deployed artifacts and not to start the app from the jenkins job folder. Then create a server log file there and start to listening to it on the jenkins window until the server started.

To do that I developed a small shell script that you can find here

You will also find a small article explaining how to configure the project on jenkins.

Please let me know if worked for you. Thnaks

The nohup and the at now + 1 minutes didn't work for me. Since Jenkins was killing the process spun in the background, I ensured the process to not be killed by setting a fake BUILD_ID to that Jenkins task. This is what the Jenkins Execute shell task looks like:

BUILD_ID=do_not_kill_me
java -jar -Dserver.port=8053 /root/Deployments/my_application.war &
exit

As discussed here.

The problem is that Jenkins doesn't handle spawning child process from builds very well. Workaround suggested by @Steve in the comment (nohuping) didn't change the behaviour in my case, but a simple workaround was to schedule app's start by using the at unix command:

> echo "mvn spring-boot:run" | at now + 1 minutes

This way Jenkins successfully completes the job without timing out.

If you end up running your application from a .jar file via java -jar app.jar be aware that Boot breaks if the .jar file is overwritten, you'll need to make sure the application is stopped before copying the artifact. If you're using ApplicationPidListener you can verify that the application is running (and stop it if it is) by adding execution of this command:

> test -f application.pid && xargs kill < application.pid || echo 'App was not running, nothing to stop'
