Store dependencies in private GitHub or Bitbucket repo - scala

Question

We are using sbt 0.13.9 and we want to use a private GitHub repo to store company-wide dependencies.
I try to add a private GitHub repo to the resolvers like this:
resolvers += Resolver.ssh("Company Repo", "git#github.com:company/company-repo.git", "/raw/master")(Resolver.ivyStylePatterns)
// or
resolvers += Resolver.ssh("Company Repo", "git#github.com:company/company-repo.git", "/raw/master")(Resolver.ivyStylePatterns) as("githubuser")
// or
resolvers += Resolver.ssh("Company Repo", "git#github.com:company/company-repo.git", "/raw/master")(Resolver.ivyStylePatterns) as("githubuser", "password")
// or
resolvers += {
val keyFile: File = new File(Path.userHome.absolutePath + "/.ssh/id_rsa")
Resolver.ssh("Company Repo", "git#github.com:company/company-repo.git", "/raw/master")(Resolver.ivyStylePatterns) as("githubuser", keyFile)
}
// or
resolvers += {
val keyFile: File = new File(Path.userHome.absolutePath + "/.ssh/id_rsa")
Resolver.ssh("Company Repo", "git#github.com:company/company-repo.git", "/raw/master")(Resolver.ivyStylePatterns) as("githubuser", keyFile, "keyFilePassword")
}
(For the resolvers where no user and/or no password was supplied a popup appears to enter the username/password.)
However, it is always failing:
[warn] ==== Company Maven Repo: tried
[warn] com.company/my-module_2.11/2.0.0/ivys/ivy.xml
The location of the files inside the repo are correct, I am 100% sure.
Can sbt handle git repos as resolvers at all? Did someone has a working example with a private GitHub repo? Bitbucket would be fine too.
Again, the repo is private and the repos is a git repo, not http(s) nor sftp.
Oh, and yes, I know bintray, but right now we don't want to pay 45 USD monthly to manage like 3 dependencies for 2 devs.
PS: My configuration is based on examples from
https://groups.google.com/forum/#!topic/maven-and-scala/dhzEZ0dR_is and
SBT doesn't use ssh-based resolver to resolve dependency
