	# 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
