container:start 停止在 Scalatra sbt 项目中工作："invalid key"

Question

我有一个使用 giter8 以标准方式构建的 scalatra 项目。

我不确定为什么 container:start 在我的 scalatra 项目中不再起作用：没有对 build.sbt 进行任何更改。这是错误：

Using /home/stephen/.sbt/0.12.0 as sbt dir, -sbt-dir to override.
[info] Set current project to wfdemo (in build file:/home/stephen/wfdemo/)
> container:start
[error] Not a valid key: start (similar: state, startYear, target)
[error] container:start
[error]

这是 sbt：

object KeywordsservletBuild extends Build {
  val Organization = "com.astralync"
  val Name = "KeywordsServlet"
  val Version = "0.1.0-SNAPSHOT"
  val ScalaVersion = "2.11.7"
  val ScalatraVersion = "2.4.0-RC2-2"

  lazy val project = Project (
    "keywordsservlet",
    file("."),
    settings = ScalatraPlugin.scalatraSettings ++ scalateSettings ++ Seq(
      organization := Organization,
      name := Name,
      version := Version,
      scalaVersion := ScalaVersion,
      resolvers += Classpaths.typesafeReleases,
      resolvers += "Scalaz Bintray Repo" at "http://dl.bintray.com/scalaz/releases",
      libraryDependencies ++= Seq(
        "org.apache.spark" %% "spark-core" % "1.3.1",
        "org.scalatra" %% "scalatra" % ScalatraVersion,
        "org.scalatra" %% "scalatra-scalate" % ScalatraVersion,
        "org.scalatra" %% "scalatra-specs2" % ScalatraVersion % "test",
        "ch.qos.logback" % "logback-classic" % "1.1.2" % "runtime",
        "org.eclipse.jetty" % "jetty-webapp" % "9.2.13.v20150730" % "container",
        "javax.servlet" % "javax.servlet-api" % "3.1.0" % "provided",
        "net.databinder" % "unfiltered-netty_2.11" % "0.8.4"
      ),
      scalateTemplateConfig in Compile <<= (sourceDirectory in Compile){ base =>
        Seq(
          TemplateConfig(
            base / "webapp" / "WEB-INF" / "templates",
            Seq.empty,  /* default imports should be added here */
            Seq(
              Binding("context", "_root_.org.scalatra.scalate.ScalatraRenderContext", importMembers = true, isImplicit = true)
            ),  /* add extra bindings here */
            Some("templates")
          )
        )
      }
    )
  )
}

感谢建议。

小但不一定明显的修复：

; container:start ; shell

前导分号是必需的。

container:start 停止在 Scalatra sbt 项目中工作："invalid key"

container:start stopped working in Scalatra sbt project : "invalid key"

scala

sbt
