SBT doesn't use ssh-based resolver to resolve dependency - sbt

Question

I have the following definition in my build.sbt:
libraryDependencies += "com.bubblefoundry" %% "something" % "0.1-SNAPSHOT"
resolvers += {
val privateKeyFile = new java.io.File(sys.env("HOME") + "/.ssh/id_rsa")
Resolver.ssh("Bubble Foundry", "bubblefoundry.com", "/usr/local/repository/") as ("peter", privateKeyFile) withPermissions("0644")
}
When sbt tries to resolve the dependency, it fails:
[info] Resolving com.bubblefoundry#something_2.10;0.1-SNAPSHOT ...
[warn] module not found: com.bubblefoundry#something_2.10;0.1-SNAPSHOT
[warn] ==== local: tried
[warn] /Users/peter/.ivy2/local/com.bubblefoundry/something_2.10/0.1-SNAPSHOT/ivys/ivy.xml
[warn] ==== Bubble Foundry: tried
[warn] ==== public: tried
[warn] http://repo1.maven.org/maven2/com.bubblefoundry/something_2.10/0.1-SNAPSHOT/something_2.10-0.1-SNAPSHOT.pom
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
[warn] :: UNRESOLVED DEPENDENCIES ::
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
[warn] :: com.bubblefoundry#something_2.10;0.1-SNAPSHOT: not found
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
It appears like it didn't even connect to the server to look for the dependency. Why is that? Am I doing something wrong?
The dependency has been published (using the same resolver definition) to /usr/local/repository/com/bubblefoundry/...

Answer 1

After updating to sbt 0.13, I can use my private repo by adding the following line to build.sbt
resolvers += Resolver.ssh("Company Maven Repo", "git#github.com:company/company-repo.git", "/raw/master")
A dialog pops up asking for my github username and password
It's a bug!
For example I am using github to host a private/internal maven repo accessed via SSH. I can pull artifacts without any difficultly when using Maven/POM files as you'd expect.
But can't get SBT (0.12.2) to work. Most frustratingly it just says
== REPO_NAME: tried
Even if I specify invalid authentication or give a bad ssh url it does the same i.e. there is no error reporting.
Spent a few hours researching and trying combinations to no avail. Therefore I suggest SSH repos don't work properly.

I found a solution: switch from ssh to sftp:
resolvers += {
val privateKeyFile = new java.io.File(sys.env("HOME") + "/.ssh/id_rsa")
Resolver.sftp("Bubble Foundry", "bubblefoundry.com", "/usr/local/repository/") as ("peter", privateKeyFile)
}
