title: How can sbt pull dependency artifacts from git?
body: <p>I've heard (and I know I've seen examples too, if only I can remember where) that <code>sbt</code> can obtain dependencies from a git repo.</p>
  
  <p>I am looking to obtain the dependency <a href="https://github.com/harrah/up" rel="noreferrer">harrah/up</a> from github. The repository does not provide any artifact JAR files, only a source tree which is set up to be built using <code>sbt</code>. The process that I am imagining is that <code>sbt</code> will download the source repo, build it, and then use that as the dependency artifact.</p>
  
  <p>I may be imagining that <code>sbt</code> can in fact do something like this. Can it? And if so, how?</p>
