title: Automatically download missing artifacts if missing in Artifactory
body: <p>I'm using Jfrog Artifactory to contain artifacts. I'm building with Maven. Is there a way to configure Maven to automatically download missing artifacts, artifacts that are not in the Artifactory repo.</p>
  
  <p>Example: <br>
  org.maven.framework-2.5.0 is downloaded from Artifactory since it exists in the Artifactory.
  org.maven.anotherframework-2.2.2 doesn't exists in Artifacotry. How to set maven to get from internet?
  <br>
  <br>
  Is it common to use Artifactory this way?</p>
