将参数传递给sbt任务

Question

我有以下sbt任务，我想将参数传递给：

import sbt.complete._
import complete.DefaultParsers._

val stageEnv: Parser[String] = " staging" 
val prodEnv : Parser[String] = " production"
val combinedParser: Parser[String] = stageEnv | prodEnv

slick := slickCodeGenTask.value

lazy val slick = inputKey[InputTask[Seq[File]]]("gen-tables")

lazy val slickCodeGenTask = Def.inputTask {
  ...
  s.log.info(combinedParser.parsed.trim)
  Seq(file(fname))
}

然而，当我运行它并传递像'sbt slick prodEnv'这样的arg时，我收到以下错误：

[error] Not a valid command: prodEnv
[error] Not a valid project ID: prodEnv
[error] Expected ':' (if selecting a configuration)
[error] Not a valid key: prodEnv (similar: products)
[error] prodEnv
[error]  

Answer 1

这有效：

import complete.DefaultParsers._

val slick = inputKey[Seq[File]]("gen-tables")

slick := {
  ...
  val arg: String = spaceDelimited("<arg>").parsed(0)
  ... 
}

致电：

sbt＆＃39; slick staging＆＃39;

sbt＆＃39; slick production＆＃39;
