// integrate buildinfo: really this can't be packaged up in the JAR as it will prevent being
// idempotent
// how can we skip whole phases or at least be consistent
// how to decorate the lifecycle with additions i.e. a DAG within a phase
// include all the dependencies in the distribution, either use it as a repository or push them to
// the local repo on startup the first time
// we ultimately want simple JSR330 components
// offline model
