the concept of a project object model (POM), Maven can manage a project's

  In the event the '-o' switch is the impetus for setting offline mode, this
  should result in modification of the active profile in the MavenSettings
  instance, just as definition of the active profile from the command-line
  should result in similar modification. This object is not meant to be
  static within the build process, but rather to be setup as an aggregation of
