title: Maven: Create Clean .m2 from Dirty .m2 to Support Offline Builds
body: <p>I have a Maven project. One of the repositories is no longer available online.</p>
  <p>My local environment has what it needs to build the project offline with -o.</p>
  <p>What's a good way to capture only the files this project needs, to provide a copy of the artifacts to others to develop the project in the same offline manner?</p>
  <p>I'd like to avoid providing my entire .m2 directory for efficiency.</p>
  <p>It would be great if there was a way to save all of the build artifacts for a particular Maven project from a bloated working .m2 to a clean .m2, including only what's necessary to the project, to easily share with others.</p>
  <p>Thanks!</p>
