create a job in jenkins

on the jenkins home page select create new jobs or New Item and create a freestyle project.

set the GitHub repository and branch

configure the jenkins job to use the spring-boot-hello-world project on the port-9000 branch

set the job to build on changes to the branch

configure poll SCM so that jenkins checks for a change on the port-9000 branch every 1 minute

configure the build script

under the build section click Add build step > Execute shell and enter the script below

# create the application jar file
mvn clean package
# copy the jar file to the spring user home
sudo cp target/hello-world-0.0.1-SNAPSHOT.jar /home/spring/app.jar
# make sure that the spring user owns the jar file
sudo chown spring:spring /home/spring/app.jar
# restart the spring service
sudo systemctl restart spring

it should look something like this in the jenkins job configuration

save the job configuration

click the Save button at the bottom of the screen
whenever a change is made to the port-9000 branch now the jenkins job will execute
