SBT publish

I'm trying to get sbt publishing from the command line to work with ProGet's maven repository system. I can successfully publish as long as I have the isSnapshot set to true, however, that doesn't seem to show up anywhere in ProGet. As soon as I set isSnapshot to false, the publish fails saying it already exists and can't be overwritten (regardless whether I change the version number or anything else).

relevant bits of build.sbt:

organization := "MyCorporation"
scalaVersion := "2.10.6"
name := "MyOrders-test"
version := "1.0.1"
publishTo := Some("packages.mycorp.com" at "http://packages.mycorp.com/maven-feeds/private-maven")
credentials += Credentials("packages.mycorp.com", "packages.mycorp.com", "myadmin", "redacted")
//isSnapshot := true

As is probably obvious in the above, my ProGet install is at http://packages.mycorp.com and the url to my maven feed is http://packages.mycorp.com/maven-feeds/private-maven.

Any ideas why I would be seeing this or any suggestions on how to work through this?

Product: ProGet
Version: 4.4.1

We actually haven't tried using SBT just yet (in fact, I just learned about it from your post).

But generally speaking, one of challenges with Maven is that it's convention-based, and doesn't have any documentation on the convention. So it's possible that SBT is using a slightly different convention than Maven or Ivy clients are. Moreover, different "packages" have a convention to behave differently...

Would you able to attach Fiddler and see where some of the discrepancies in the request/responses might be? Sometimes it's incredibly obvious, and that might allow us to implement yet another undocumented convention. It may be easier to communicate over email, so perhaps fill out a ticket or just email us at support-at-Inedo-com once you have some details?
