Question

我正在尝试使用lift web框架设置scala sbt项目。我正在使用

scala 2.9.0-1
sbt 0.10.1
lift 2.3
xsbt-web-plugin 0.1.1（仅在scala 2.8.1上，见问题末尾）

（我知道最近的版本）。我跟着http://d.hatena.ne.jp/k4200/20110711/1310354698和https://github.com/siasia/xsbt-web-plugin/blob/master/README.md获取了以下sbt配置文件：

项目/ build.properties

sbt.version=0.10.1

项目/插件/ build.sbt

resolvers += "Web plugin repo" at "http://siasia.github.com/maven2"

libraryDependencies <+= sbtVersion(v => "com.github.siasia" % "xsbt-web-plugin_2.8.1" % ("0.1.1-"+v))

项目/ Build.scala

import sbt._
import Keys._

object BuildSettings {
  val buildOrganization = "xbaz"
  val buildScalaVersion = "2.9.0-1"
  val buildVersion      = "0.0.1"

  val buildSettings = Defaults.defaultSettings ++ Seq (
    organization := buildOrganization,
    scalaVersion := buildScalaVersion,
    version      := buildVersion)
}

object Resolvers {
  val webPluginRepo = "Web plugin repo" at "http://siasia.github.com/maven2"
  val jettyRepo = "Jetty Repo" at "http://repo1.maven.org/maven2/org/mortbay/jetty"
}

object Dependencies {

 // web plugin
  val webPluginDeps = Seq(
    "org.mortbay.jetty" % "jetty" % "6.1.26" % "jetty", // The last part is "jetty" not "test".
    "javax.servlet" % "servlet-api" % "2.5" % "provided->default"
  )

  val liftDeps = {
    val liftVersion = "2.3" // I'll switch to 2.3 soon!
    Seq(

  val logDeps = Seq(grizzled, log4j_over_slf4j, logback_core, logback_classic)
}


object MyBuild extends Build {
  import com.github.siasia.WebPlugin._ // web plugin
  import BuildSettings._
  import Dependencies._
  import Resolvers._

  //End dependencies

  lazy val root = Project("root", file(".") , settings = buildSettings ++
    Seq( name := "foo")
  ) aggregate(core, cli, web)
    //  mainClass:= Some("Main"))

  lazy val core : Project = Project("core", file("core"), delegates = root :: Nil, settings = buildSettings ++
    Seq(
    name := "foo-core",
    libraryDependencies ++= logDeps ++ Seq(scalaTest, apacheHttpClient, apacheHttpCore)
    )
  )

  lazy val cli: Project = Project("cli", file("cli"), settings = buildSettings ++ 
    Seq(
    name := "foo-cli",
    libraryDependencies ++= logDeps ++ Seq(apacheHttpClient),
    fork in run := true,
    javaOptions in run += "-Djava.library.path=/home/jolivier/Projets/asknow/lib/jnotify-lib-0.93"
  )) dependsOn(core) settings(
  )

  lazy val web: Project = Project("web", file("web"), settings = buildSettings ++
    Seq (resolvers := Seq(webPluginRepo, jettyRepo),
    name := "foo-http",
    libraryDependencies ++= logDeps ++ webPluginDeps ++ liftDeps
    ) ++ 
    webSettings
  ) dependsOn(core)
}

当我尝试使用sbt jetty-run时，我收到以下错误消息：

[error] Not a valid command: jetty-run
[error] Not a valid project ID: jetty-run
[error] Not a valid configuration: jetty-run
[error] Not a valid key: jetty-run (similar: jetty-port, jetty-context, run)
[error] jetty-run
[error]

所以我注意到一些jetty- *命令确实存在，但不是我想要的那个，所以我打印了webSettings，它应该包含所有这些新设置，它包含jetty-context和jetty-port，以及jetty - 配置和其他，但不是码头运行：s。

没有码头跑我怎么了？

我尝试切换到scala-2.8.1，因为web插件目前只在scala 2.8.1上，通过更改我的buildScalaVersion变量但没有改变任何东西。你有什么想法吗？

提前感谢您的帮助

汇总任务;命令不是。

jetty-run是一个命令。它仅在具有Web插件设置的子项目的上下文中可用。

> project web
> jetty-run

运行后，您可以使用prepare-webapp任务重新部署Web应用程序。这可以从root项目的上下文运行，因为它聚合了Web项目。

sbt web plugin：不是有效密钥：jetty-run（类似：jetty-port，jetty-context，run）
