*** DefaultLifecycleExecutor

  When binding goals to the project's configured lifecycle, each mojo
  descriptor should declare whether it requires online/offline status.
  This value should be a java.lang.Boolean, so it can implement 3VL
  (three value logic: yes, no, don't-care). The requiresOnline
  field in the mojo descriptor has the following semantics:

  [true] Online status is required for this mojo to function
         correctly.

 could encapsulate everything we need about the project in the POM including
 plugin parameters and anything else.

 We once had a document that Vincent and I agreed upon and I was about to
 implement it and then I disappeared for 8 months so it never came to pass.

 So I guess it's important to figure out what people are using properties
 files for and see if we can't incorporate it all into the POM. Or if we do
