how do I get sbt to gather all the jar files my code depends on into one place?

I'm new to . I want it to put all the dependency jar files as well as my jar file into one place. SBT will run the app, but I've got various dependencies scattered around and an .ivy folder full of things my jar file depends on indirectly.

So Is there a simple command to copy them all into a single place so I can distribute it to another machine?

Add the following line to your build.sbt file. 

retrieveManaged := true

This will gather the dependencies locally

There are many plugins you can use: sbt-assembly, sbt-proguard, sbt-onejar, xitrum-package etc.

See the list of SBT plugins.

You could also try SBT Native Packager: https://github.com/sbt/sbt-native-packager (sbt 0.7+)

This is still a WIP but will be used in Play Framework 2.2 in the coming weeks. With this, you can create standalone ZIP files, Debian packages (DEB), Windows installation packages (MSI), DMG, RPM, and so on.

Try sbt-pack plugin https://github.com/xerial/sbt-pack, which collects all dependent jars in target/pack folder and also generates launch scripts.

Create a task in your build file like this:

lazy val copyDependencies = TaskKey[Unit]("pack")

def copyDepTask = copyDependencies <<= (update, crossTarget, scalaVersion) map {
  (updateReport, out, scalaVer) =>
    updateReport.allFiles foreach {
      srcPath =>
        val destPath = out / "lib" / srcPath.getName
        IO.copyFile(srcPath, destPath, preserveLastModified = true)
    }
}

Add the Task to a Project like this:

lazy val HubSensors =
  Project("HubSensors", file("HubSensors"), settings = shared ++ Seq(
    copyDepTask,
    resolvers ++= Seq(novusRels),
    libraryDependencies ++= Seq(
      jodatime
    )
  )) dependsOn(HubCameraVision, JamServiceProxy, HubDAL)

In the SBT console type:

project [Project Name]
pack
