title: Maven and dependencies NOT in repository
body: <p>We have a dependency third-party library that is available online in jar form, but it is <em>not</em> in Maven Repository, or known to be in any other repository.</p>
  
  <p>How can we use pom.xml to auto-retrieve this dependency, based on a URL?</p>
  
  <p>We don't want to store it in our Git repo, because that's A Bad Thing.</p>
  
  <p>The idea here is that when people check out the project, they can use their IDE Maven integration (or just mvn command line tools) to download all the dependencies. So we would want to be able to also download this other third party dependency just like all the ones in Maven repo.</p>
  
  <p>I have not been able to come up with an answer to this based on searches -- all solutions seem to be "download it first and create a local repo." Obviously Maven can download from the Internet, since that's how it connects to Maven Central and other repos. So I don't see why it cannot download arbitrary URLs that present packages in recognizable formats.</p>
