Maven Central

Repackage a given jar file using Jar Jar Links.

Add the following declaration to project/plugins.sbt:

addSbtPlugin("com.tapad" % "sbt-jarjar" % "1.0.3")

Example integration with sbt-assembly

Ensure that your project also includes the sbt-assembly plugin.

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.11.2")
import sbtassembly.Plugin._
import AssemblyKeys._
import sbtjarjar._
import JarJarPlugin._

val myProject = Project("my-project", file("."), settings = assemblySettings ++ jarjarSettings ++ Seq(
  jarName in assembly := "my-project.jar",
  mainClass in (Compile, run) := Some("myproject.Boot"),
  mainClass in assembly := Some("myproject.Boot"),
  jarjar <<= jarjar dependsOn assembly,
  JarJarKeys.jarName in jarjar <<= jarName in assembly,
  JarJarKeys.rules in jarjar := Seq(
    "rule myproblem.** myproblem.nolonger.@1"

Projects using sbt-assembly version 0.14.0 and greater can receive the same functionality via the built-in shading support. For more information see
