Using SBT 0.13.8, I was able to replace the next line in mine. /project/plugins.sbt:
addSbtPlugin("net.ground5hark.sbt" %% "sbt-concat" % "0.1.8")
with the following two lines
lazy val root = (project in file(".")).dependsOn(concatPlugin) lazy val concatPlugin = uri("https://github.com/ground5hark/sbt-concat.git#342acc34195438799b8a278fda94b126238aae17")
There were no other steps. Also, note that the git URI has a commit hash at the end. This is very useful for the project to use the specific version of the source known in the work, rather than any last unknown state of the source.
