    - Must be in Java package form with no dashes (ex: com.example.app)
    - It must have at least two segments (one or more dots).
    - Each segment must start with a letter.
    - All characters must be alphanumeric or an underscore [a-zA-Z][a-zA-Z0-9]+.

    If you would like to skip validation, run "cap init" with the "--skip-appid-validation" flag.
