sbt 0.10下收集依赖(将所有依赖jar放到target/scala-version/lib/) [英] Collecting dependencies under sbt 0.10 (putting all dependency jars to target/scala-version/lib/)

问题描述

我在 Scala 2.9.1 中使用 sbt 0.10.

I'm using sbt 0.10 with Scala 2.9.1.

我读过http://groups.google.com/group/simple-build-tool/browse_thread/thread/792e5360877e78/987b6af687b8e33b?lnk=gst&q=collect+jars#987b6af687b8e33b

但是我不想要一个大罐子.我只想要依赖 jars最终在 target/scala-2.9.1.final/lib 目录中.

However I don't want a one huge jar. I just want dependency jars ending up in target/scala-2.9.1.final/lib directory.

我不想要一个大罐子的原因，那个项目使用了很多libs，通常只有应用程序 .jar 更改.然而作为这是多语言项目，并非所有团队成员都有 scala 或 sbt，jars 只是提交给 git.拥有一个巨大的 dar 更新规则会增加回购规模.

The reason why I don't want a one huge jar, that project uses a lot of libs, and usually only the application .jar changes. However as this is multi-language project and not all team members have scala or sbt, jars are just commited to git. Having one huge dar updated regullary would inflate repo size.

如何复制这些依赖项?;)

How can I copy those dependencies? ;)

推荐答案

您没有指定要从中复制配置的 ivy 配置，但这里有一个完整的示例，它将复制所有您的托管依赖项到 target//lib 文件夹(scala 版本由 crossTarget 任务给出).只需复制它并将其放入文件 project/Build.scala(或您想要的任何文件名):

You didn't specify the ivy configuration to copy the configurations from but here's a fully working example that will copy all your managed dependencies to the target/<scala version>/lib folder (scala version is given by the crossTarget task). Just copy this and put it in the file project/Build.scala (or whatever filename you want) :

import sbt._
import Keys._

object MyBuild extends Build {

  lazy val copyDependencies = TaskKey[Unit]("copy-dependencies")

  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)
    }
  }

  lazy val root = Project(
    "root",
    file("."),
    settings = Defaults.defaultSettings ++ Seq(
      copyDepTask
    )
  )
}

如果需要特定配置，请替换

If you want a specific configuration, replace

updateReport.allFiles by updateReport.select(configuration = Set("compile")) 或任何你想要的常春藤配置.

updateReport.allFiles by updateReport.select(configuration = Set("compile")) or whatever ivy configuration you want.
