sbt.ResolveException: unresolved dependency: com.projectseptember#freek_2.11;0.6.7: not found

[epiphyllum]

can not pull this dependency.

could you please give me a hint on how to set my build.sbt for this dependency?

my build.sbt is as follow:

name := "free-monad-coproduct-example"

version := "1.0"

scalaVersion := "2.11.8"

lazy val `free-monad-coproduct-example` =
  (project in file("."))
    .settings(Seq(addCompilerPlugin("com.milessabin" % "si2712fix-plugin_2.11.8" % "1.2.0")))

resolvers += Resolver.jcenterRepo
// resolvers += Resolver.bintrayRepo("projectseptemberinc", "maven")

libraryDependencies ++= {
  Seq(
    "org.typelevel"             %% "cats"     % "0.8.1",
    "com.projectseptember"      %% "freek"    % "0.6.7"
  )
}

That seems really odd, have you tried resolving the dependencies on a different network to see whether maybe your network is blocking JCenter?

[calvinlfer]

Also did

resolvers += Resolver.bintrayRepo("projectseptemberinc", "maven")

do anything for you?
I updated the project to use the latest stable version of Scala (2.12.2) as of today (2017-04-19) and updated to the current version of FreeK.
