Unresolved `restlet` sbt dependency - scala

Question

I am trying to add the blueprints-sail-graph (located here) dependency via sbt, and it is having trouble resolving one of the sail dependencies. I am new to Java/Scala development and will really appreciate your help! The following is my build.sbt file:
scalaVersion := "2.10.3"
libraryDependencies ++= Seq(
"org.scalatest" % "scalatest_2.10" % "2.0" % "test" withSources() withJavadoc(),
"org.scalacheck" %% "scalacheck" % "1.10.0" % "test" withSources() withJavadoc(),
"com.tinkerpop.blueprints" % "blueprints-rexster-graph" % "2.6.0" withSources() withJavadoc(),
"com.tinkerpop.blueprints" % "blueprints-sail-graph" % "2.5.0"
)
unmanagedBase := baseDirectory.value / "lib"
resolvers += "Sonatype OSS Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots"
resolvers += "Scala-Tools Maven2 Snapshots Repository" at "http://scala-tools.org/repo-snapshots"
resolvers += "Local Maven Repository" at "file://"+Path.userHome.absolutePath+"/.m2/repository"
resolvers += "JBoss repository" at "https://repository.jboss.org/nexus/content/repositories/"
The error I get from sbt is:
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
[warn] :: UNRESOLVED DEPENDENCIES ::
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
[warn] :: org.restlet.jse#org.restlet;2.1.1: not found

I know that the sail dependency is the issue becuase if I remove it, sbt compiles without a problem. I added the additional resolvers hoping that one of them would contain this jar -- in fact JBoss appears to, but for some reason it still did not work. I also tried many different versions of blueprints-sail-graph unsuccessfully. I am not sure what else to do, please help me get this dependency resolved.
Thanks for all the help!
EDIT: According to another post, this jar needs to be specifically added to Ivy -- hope that saves someone some time. I tried a few things with Ivy but did not succeed :(

Add the following to list of resolvers:
resolvers += "Restlet Repositories" at "http://maven.restlet.org"
By the way you can use sbt predefined attributes. The whole sbt build file will be like this:
import sbt.Resolver.mavenLocal
scalaVersion := "2.10.3"
unmanagedBase := baseDirectory.value / "lib"
resolvers ++= Seq(
mavenLocal,
"Restlet Repository" at "http://maven.restlet.org/",
"JBoss Repository" at "https://repository.jboss.org/nexus/content/repositories/",
"Sonatype Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots/",
"Scala-Tools Snapshots" at "http://scala-tools.org/repo-snapshots/"
)
libraryDependencies ++= Seq(
"org.scalatest" % "scalatest_2.10" % "2.0" % "test" withSources() withJavadoc(),
"org.scalacheck" %% "scalacheck" % "1.10.0" % "test" withSources() withJavadoc(),
"com.tinkerpop.blueprints" % "blueprints-rexster-graph" % "2.6.0" withSources() withJavadoc(),
"com.tinkerpop.blueprints" % "blueprints-sail-graph" % "2.5.0"
)
