cat /etc/systemd/system/homepro-backend.service
sudo systemctl start homepro-backend
sudo systemctl enable homepro-backend // < --- to have it start by default
sudo systemctl status homepro-backend

check Backend logs

tail -f logs/app.json

run backend without service

sudo java -jar http-assembly-0.1.0.jar
