SBT doesn't seem to find dependencies in ftp repository - scala

Question

I'm migrating some java+maven projects to scala+sbt but I've been having some troubles to make sbt work with my maven repository.
I'm using sbt 0.13.5 and my build.sbt looks like this:
name := "test"
version := "0.0.1"
resolvers += "uqbar-repo" at "ftp://mvn+uqbar-wiki.org:<my_password>#ftp.uqbar-wiki.org/releases"
libraryDependencies += "uqbar" % "uqbar-commons" % "1.1"
As you may see, my dependencies are hosted in an ftp server (ssh is not available so just ftp, NOT sftp) and there seems to be no problem to access them from maven, but running sbt yields the following error:

I found this weird, since the files are there (pom can be accessed from the url sbt tried, even from a browser) so I used a sniffer to check what was actually being send and receive. The output I got was:

Now, my ftp is a little rusty, but that log seems to indicate that sbt found and download the pom.
In case it is of any use, here is the pom content:

I've search the documentation but found nothing and I have no idea where the problem may be, so any hint is welcome.
Thanks in advance!
