> I'm new to M2, so this may be user error, but even still, I think a more useful error message would be appropriate.
> I'm trying to deploy my project to an internal Remote Repository using SCP or SFTP (SCP fails with the "session is down" message, so I'm trying SFTP).  I get the attached trace during my build.  I'm not exactly sure what metadata it's hoping to find.
