SBT plugin for collecting dependency .jar files for standalone Scala programs

Scala versions: 2.12 2.10
sbt plugins: 1.0 0.13

This plugin adds task xitrumPackage to your SBT project to collect all dependency .jar files for standalone Scala programs.

Compared to one-jar solutions, xitrum-package is faster. It doesn't merge the .jar files together, the .jar files are left "as is".

xitrum-package is used in Scala web framework Xitrum.

Alternatively, you can use sbt-pack.

Usage

Suppose your project looks like this:

build.sbt

project/
  plugins.sbt

src/
  ...

dirToCopy/      <-- Directory you want to copy to the packaged directory
  file1
  file2

fileToCopy      <-- File you want to copy to the packaged directory

Add xitrum-package to your project

Add to project/plugins.sbt:

addSbtPlugin("tv.cntt" % "xitrum-package" % "1.9")

Add to build.sbt:

XitrumPackage.copy("dirToCopy", "fileToCopy")

Do the packaging

Run:

sbt xitrumPackage

All dependency .jar files and .jar files generated from your project will be copied to directory target/xitrum:

target/
  xitrum/
    lib/        <-- Dependency .jar files are collected here
      dep1.jar
      dep2.jar
      yourProject.jar

    dirToCopy/  <-- The specified directory is copied here
      file1
      file2

    fileToCopy  <-- The specified file is copied here

Note that even when you don't need to copy anything, you have to write in build.sbt:

XitrumPackage.copy()

Multimodule project

If your SBT project has many modules (subprojects) and you want to add xitrum-package to only several of them, you can use XitrumPackage.skip:

// Shared settings used by many modules
val sharedSettings = ...

// For the default root project
override lazy val settings = super.settings ++ XitrumPackage.skip

// If you want to skip this module
lazy val module1 = Project(
  id = "module1",
  base = file("module1"),
  settings = sharedSettings ++ Seq(
    name := "module1"
  ) ++ XitrumPackage.skip
)

// If you want to xitrum-package this module
lazy val app = Project(
  id = "main-app",
  base = file("main-app"),
  settings = sharedSettings ++ Seq(
    name := "main-app"
  ) ++ XitrumPackage.copy("bin", "config", "public")
).dependsOn(module1)

Boot script

You should create a shell script to start your Scala program like this:

Run example:

runner.sh mypackage.MyMainClass
