Question

我想创建一个执行传递本地的任务，然后将.xml文件的副本复制到项目根目录中的ivy.xml。我希望它可以从每个sbt命令行获得，所以我把它放在〜/ .sbt / 0.13 / plugins中。

我对如何引用deliverLocal中的值感到困惑。如果我这样做：

import sbt._
import Keys._

object JivyBuild extends Build {

lazy val jivy = TaskKey[String] ( "jivy", "Copy the ivy file created by deliverLocal to ivy.xml" )

lazy val jivyTask = jivy := {
  val ivyFile = deliverLocal.value
  com.google.common.io.Files.copy(ivyFile, baseDirectory.value / "ivy.xml")
  println(s"base dir is " + baseDirectory.value.toString)
  ivyFile.toString
}

    override lazy val settings = super.settings ++
        Seq(jivyTask, resolvers := Seq())

    lazy val root = Project(id = "root",
                            base = file("."),
                            settings = Project.defaultSettings ++ settings)
}

当我开始sbt：

时出现此错误

[error] Reference to undefined setting: 
[error] 
[error]   {.}/*:deliverLocal from {.}/*:jivy (/Users/james/.sbt/0.13/plugins/Jivy.scala:8)
[error]      Did you mean *:deliverLocal ?
[error]  
[error] Use 'last' for the full log.

您正在覆盖默认设置，因此deliverLocal设置被删除。不要改变：

override lazy val settings = super.settings ++
    Seq(jivyTask, resolvers := Seq())

类似于：

lazy val mysettings = super.settings ++
    Seq(jivyTask, resolvers := Seq())

在root中引用它而不是settings：

lazy val root = Project(id = "root",
                        base = file("."),
                        settings = Project.defaultSettings ++ mysettings)

如何在sbt 13中引用.scala文件中的任务？
