# Each stages executes in sequence, if previous job fails, then all the preceeding jobs are skipped.
stages:
  - backend_build

# tags: "shell" should match with the tag name provided to runner, for spring runner should execute in shell.
# Notice that in petclinic project, the spring project is in root of master, if yours is in folder then cd to that folder.

# artifacts are created when job executes successfully, and can be manually downloaded from GitLab GUI.

# Below stage builds, deploys and executes the jar as service.
# Make sure there is /target directory in your server, else script will fail, or use any other folder you like.
# If you are changing the folder, reflect the change in systemd-web-demo service too.
