scala - 使用简单构建工具制作独立jar

Question

有没有办法告诉sbt将所有需要的库(scala-library.jar)打包到主包中，所以它是独立的？ (静态的？)

Answer 1

编辑2011:
从那时起，retronym(发布了answer in this page back in 2010)将该sbt-plugin "sbt-onejar"更改为new address on GitHub，并将文档更新为SBT 0.12。

Packages your project using One-JAR™

onejar-sbt is a simple-build-tool plugin for building a single executable JAR containing all your code and dependencies as nested JARs.
Currently One-JAR version 0.9.7 is used. This is included with the plugin, and need not be separately downloaded.

原始答案:
直接地，如果不扩展sbt(在 custom action模型之后的 "package" sbt action)，这是不可能的。
GitHub mentions an assembly task，为 jetty 部署量身定制。您可以根据需要进行调整。
code is pretty generic(来自 this post和用户Rio):

 project / build / AssemblyProject.scala

 import sbt._
 
 trait AssemblyProject extends BasicScalaProject
 {
         def assemblyExclude(base: PathFinder) = base / "META-INF" ** "*"
         def assemblyOutputPath = outputPath / assemblyJarName
         def assemblyJarName = artifactID + "-assembly-" + version + ".jar"
         def assemblyTemporaryPath = outputPath / "assembly-libs"
         def assemblyClasspath = runClasspath
         def assemblyExtraJars = mainDependencies.scalaJars
 
         def assemblyPaths(tempDir: Path, classpath: PathFinder, extraJars: PathFinder, exclude: PathFinder => PathFinder) =
         {
                 val (libs, directories) = classpath.get.toList.partition(ClasspathUtilities.isArchive)
                 for(jar <- extraJars.get ++ libs) FileUtilities.unzip(jar, tempDir, log).left.foreach(error)
                 val base = (Path.lazyPathFinder(tempDir :: directories) ##)
                 (descendents(base, "*") --- exclude(base)).get
         }
         
         lazy val assembly = assemblyTask(assemblyTemporaryPath, assemblyClasspath, assemblyExtraJars, assemblyExclude) dependsOn(compile)
         def assemblyTask(tempDir: Path, classpath: PathFinder, extraJars: PathFinder, exclude: PathFinder => PathFinder) =
                 packageTask(Path.lazyPathFinder(assemblyPaths(tempDir, classpath, extraJars, exclude)), assemblyOutputPath, packageOptions)
 }
