title: Maven: How to deploy with deploy-file and custom wagon
body: <p>I'm trying to use a custom maven wagon extension to deploy a jar to my own repository. Can I somehow configure in settings.xml that it recognizes the custom url scheme to be used with the specific wagon or do I have to always modify pom files to contain the wagon extension?</p>

  <p>There doesn't need to be a base pom or any pom available when using the deploy-file. Settings.xml is the only place which is guaranteed to be there, but I can't figure out how to use it to define extensions.</p>
