将任务添加到 Build.scala [英] Add task to Build.scala

问题描述

文档http://www.scala-sbt.org/0.13.0/docs/Detailed-Topics/Tasks.html 解释了如何向 build.sbt 添加任务，但如何向 build.scala 添加任务?谢谢

The document http://www.scala-sbt.org/0.13.0/docs/Detailed-Topics/Tasks.html explains how to add a task to build.sbt, but how do you add one to build.scala? Thanks

推荐答案

声明 TaskKey 的部分在两种格式中都是相同的:val myTask = taskKey...代码>.

The part where you declare the TaskKey is the same in either format: val myTask = taskKey....

您写出Initialize[Task[T]] 的部分是相同的:myTask := ....

The part where you write out your Initialize[Task[T]] is the same: myTask := ....

唯一的区别是后者出现的上下文.

The only difference is the context in which the latter thing appears.

在.sbt格式中，它自己出现，用空行与其他东西分开.

In the .sbt format, it appears by itself, separated from other things by blank lines.

在 .scala 格式中，您必须将设置添加到项目中.这记录在 http://www.scala-sbt.org/release/docs/Getting-Started/Full-Def.html 并且无论我们谈论的是任务还是常规设置都是一样的.

In the .scala format, you have to add the setting to the project. That's documented at http://www.scala-sbt.org/release/docs/Getting-Started/Full-Def.html and is the same regardless of whether we're talking about a task or a regular setting.

这是一个完整的工作示例:

Here's a complete working example:

import sbt._
object MyBuild extends Build {
  val myTask = taskKey[Unit]("...")
  lazy val root =
    Project(id = "MyProject", base = file("."))
      .settings(
        myTask := { println("hello") }
    )
}
