Offline Mode Design

* UPDATE: 18-April-2005

  We cannot take the approach outlined below of detecting which remote
  repositories are "really" offline, since offline mode is more of a behavior,
  and this will lead to counter-intuitive results. A different feature may exist

            if (MojoExecution.Source.CLI.equals(mojoExecution.getSource())) {
                Throwable cause = new IllegalStateException(
                        "Goal requires online mode for execution" + " but Maven is currently offline.");
                throw new LifecycleExecutionException(
                        messageBuilderFactory, mojoExecution, session.getCurrentProject(), cause);
            } else {

the Classpath Exception to the necessary parts of its GPLv2 code, which
permits you to use that code in combination with other independent
modules not licensed under the GPLv2.  However, note that this would
not permit you to commingle code under an incompatible license with
Oracle's GPLv2 licensed code by, for example, cutting and pasting such
code into a file also containing Oracle's GPLv2 licensed code and then
