      # Maven command-line options:
      # --batch-mode: recommended in CI to inform maven to not run in interactive mode (less logs)
      # -V: strongly recommended in CI, will display the JDK and Maven versions in use.
      # -Dsurefire.useFile=false: useful in CI. Displays test errors in the logs directly (instead of
      #                           having to crawl the workspace files to see the cause).
      # -e: Display stack-traces on failure
