title: How can I prevent previously deployed artifacts from being overwritten?
body: <p>We use Artifactory for our company's Maven repository.  Is there a way to set it up (or set Maven up) so that an artifact can't be deployed to the repository if there is a pre-existing artifact with the same version number?</p>
  
  <p>The reasoning for this is to make sure that valid releases don't accidentally get overwritten.  If an artifact really does need to be re-deployed, one of our developers can use the Artifactory web interface to delete it.  Then they can deploy the new copy.</p>
  
  <p>Thanks!</p>
