如何在多模块项目中通过sbt调用npm

我正在使用sbt构建多模块项目。其中一个模块是一个使用npm构建的JavaScript应用程序。我想简单地通过shell脚本执行npm作为包任务的一部分，并使用生成的输出文件作为该模块的工件。我能够运行shell命令作为程序包任务的一部分，但由于某些原因，当我运行publish或publishLocal时，将忽略此任务。如何在多模块项目中通过sbt调用npm

附加的是我的Build.scala。

这是accounts-ui项目，应该使用npm构建。现在，实际的npm构建由一个简单的脚本表示。

import sbt._ 
import Keys._ 
import play.Play.autoImport._ 
import PlayKeys._ 
import play.PlayScala 
import sbtassembly._ 
import AssemblyKeys._ 
import net.virtualvoid.sbt.graph.Plugin.graphSettings 
import ohnosequences.sbt.SbtS3Resolver.autoImport._ 

object Build extends Build { 

    lazy val commonSettings = Seq(
    organization := "myorg", 
    scalaVersion := "2.11.5" 
) 

    lazy val publishSettings = Seq(
    publishTo := { 
     val prefix = if (isSnapshot.value) "snapshots" else "releases" 
     Some(s3resolver.value("MyOrg " + prefix + " S3 bucket", s3(prefix+".repo.myorg.com"))) 
    } 
) 

    lazy val root = Project(id = "root", base = file(".")).settings(commonSettings).settings(
    name := "accounts-root" 
).settings(publishSettings).aggregate(api, ui) 

    val _apiName = "accounts-api" 

    lazy val api = Project(id = "api", base = file("./api")).settings(commonSettings).settings(
    name := "accounts-api", 
    libraryDependencies ++= Seq(
     specs2 
    ) 
).settings(publishSettings).settings(graphSettings).settings(
    mainClass in assembly := Some("play.core.server.NettyServer"), 
    fullClasspath in assembly += Attributed.blank(PlayKeys.playPackageAssets.value), 
    test in assembly := {}, 
    assemblyExcludedJars in assembly := { 
     val cp = (fullClasspath in assembly).value 
     cp filter { (el) => { 
      val name = el.data.getName 
      name.contains("mockito") || name.contains("commons-logging") || name.contains("specs2") 
     } 
     } 
    } 
).settings(addArtifact(Artifact(_apiName, "assembly"), assembly) 
).enablePlugins(PlayScala) 

    val npmBuildTask = taskKey[Unit]("some custom task") 

    lazy val ui = Project(id = "ui", base = file("./ui")).settings(commonSettings).settings(
    name := "accounts-ui", 
    npmBuildTask := { 
     val processBuilder = Process("npm-build.sh") 
     val process = processBuilder.run() 
     if(process.exitValue() != 0) 
     throw new Error(s"custom task failed with exit value ${process.exitValue()}") 
    }, 
    Keys.`package` <<= (Keys.`package` in Compile) dependsOn npmBuildTask 
).settings(publishSettings) 

}

我能解决这个问题如下：

val npmPackageTask = taskKey[File]("npm package task") 

    lazy val ui = Project(id = "ui", base = file("./ui")).settings(commonSettings).settings(
    name := "accounts-ui", 
    npmPackageTask := { 
     val processBuilder = Process("npm-build.sh") 
     val process = processBuilder.run() 
     if(process.exitValue() != 0) 
     throw new Error(s"custom task failed with exit value ${process.exitValue()}") 
     file(".") 
    }, 
    packageBin in Compile <<= npmPackageTask 
).settings(publishSettings)

的关键是创建密钥taskKey [文件]，使用packageBin键，并更换与< <任务=运营商。
