I have a maven2 repository from which I\'m trying to fetch an snapshot artifact with an appended timestamp. I\'m (unsurprisingly) able to retrieve it fine when building with
Alright, I got this sorted out but it wasn't actually an SBT problem it was 100% user error.
The Nexus I was using required authentication. I didn't have the authentication credentials set up correctly (see my authentication question) and because it wasn't properly authenticating it wasn't finding the metadata pom files and so SBT printed out the error message that it was failing I, incorrectly, assumed it was authenticating but not resolving. So I started messing with the patterns as evidenced in the actual question.
However, now that I have authentication setup correctly I changed back to just a regular repository declaration like so:
val snapshotsRepo = "Snapshots Repository" at "http://host:port/path/to/snapshots/root/"
and everything works. Artifacts are retrieved and dependencies resolved.
