    // Apache Maven related side notes:
    // --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.
    //      Very useful to be quickly sure the selected versions were the ones you think.
    // -U : force maven to update snapshots each time (default : once an hour, makes no sense in CI).
    // -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).

    // Advice: don't define M2_HOME in general. Maven will autodetect its root fine.
