            The important difference is this will not resolve the files for the dependencies, i.e. the artifacts
            associated with a Maven project can lack a file. As such, this annotation is meant for Mojos that only
            want to analyze the set of transitive dependencies, in particular during early lifecycle phases where

r.java /** * The TypeSafe classes, and their descendants, need a mechanism to find out what type has been used as a parameter * for the concrete matcher. Unfortunately, this type is lost during type erasure so we need to use reflection * to get it back, by picking out the type of a known parameter to a known method. * The catch is that, with bridging methods, this type is only visible in the class that actually implements * the expected method, so the ReflectiveTypeFinder needs to be applied to that...

  behaviors behind a consistent user interface is much, much more difficult if
  the system can't tell whether it has access to the network required by these
  operations.

  Offline mode really means anticipating a lack of network connectivity, and as
  a result turning off certain services provided by m2 and providing a coherent
  way of predicting and reporting when network-related failures will take place.
