Description

Try using ftp-wagon to deploy a project to a remote repository that requires a username/password for login. Make sure you have no settings.xml file. You get this stack trace:

Wagon should tell you the real cause of the problem: "Please supply authentication information in your settings.xml file." Something like that.
