Sbt 0.13到1.0 - 在多項目中，Global的onLoad替代項目是什麼？

Question

我正在嘗試創建一個新項目，這次是使用sbt 1.0.2而不是0.13.x，我現在用了很長一段時間。

在那裏，我不得不https://github.com/vmunier/akka-http-with-scalajs-example/blob/master/build.sbt

我的問題多的項目設置可比現在是我總是得到[error] (projectname/compile:bgRun) No main class detected.當我嘗試運行sbt run

這裏是我當前build.sbt文件：

lazy val generalSettings = Seq(
    name := "awesomeproject.tld", 
    version := "0.1", 
    scalaVersion := "2.12.3" 
) 

lazy val client = (project in file("modules/client")) 
    .settings(generalSettings: _*) 
    .settings(
    name := "client", 
    libraryDependencies ++= Seq(
     "com.lihaoyi" %%% "scalatags" % "0.6.5", 
     "org.scala-js" %%% "scalajs-dom" % "0.9.2" 
    ) 
    , scalaJSUseMainModuleInitializer := true 
) 
    .enablePlugins(ScalaJSPlugin, ScalaJSWeb) 
    .dependsOn(sharedJS) 

lazy val server = (project in file("modules/server")) 
    .settings(generalSettings: _*) 
    .settings(
    name := "server", 
    scalaJSProjects := Seq(client), 
    pipelineStages in Assets := Seq(scalaJSPipeline), 
    // triggers scalaJSPipeline when using compile or continuous compilation 
    //compile in Compile := ((compile in Compile) dependsOn scalaJSPipeline).value, 
    WebKeys.packagePrefix in Assets := "public/", 
    //managedClasspath in Runtime += (packageBin in Assets).value, 
    libraryDependencies ++= Seq(
     "com.typesafe.akka" %% "akka-actor" % "2.5.4", 
     "com.typesafe.akka" %% "akka-testkit" % "2.5.4" % Test, 
     "com.typesafe.akka" %% "akka-stream" % "2.5.4", 
     "com.typesafe.akka" %% "akka-stream-testkit" % "2.5.4" % Test, 
     "com.typesafe.akka" %% "akka-http" % "10.0.10", 
     "com.typesafe.akka" %% "akka-http-testkit" % "10.0.10" % Test, 

     "ch.qos.logback" % "logback-classic" % "1.2.3", 
     "com.typesafe.scala-logging" %% "scala-logging" % "3.7.2", 

     "com.lihaoyi" %% "scalatags" % "0.6.5", 
     "com.vmunier" %% "scalajs-scripts" % "1.1.0" 
    ) 

    , mainClass := Some("tld.awesomeproject.Main") 
) 
    .dependsOn(sharedJVM) 

lazy val shared = (crossProject.crossType(CrossType.Pure) in file("modules/shared")) 
    .settings(generalSettings: _*) 
    .settings(
    name := "shared" 
) 

lazy val sharedJS = shared.js 
lazy val sharedJVM = shared.jvm 

正如你所看到的，我試圖解決這個問題，並在子版中用mainClass := Some("tld.awesomeproject.Main")明確設置項目。我也嘗試明確地設置一個根項目，使其依賴於服務器，但沒有運氣。

我在這裏想真正的問題是，

onLoad in Global := (Command.command("project server", _: State)) compose (onLoad in Global)不SBT 1.0.2工作了。

我檢查了Command班，但我並不聰明。根本沒有更多的方法可以回饋一個國家。

任何人都可以擺脫這樣嗎？我想要的是運行一個向客戶端發送一些javascript的服務器......這不應該是黑魔法，事實上，在我的0.13版本中，所有的東西都像魅力一樣。項目。

這應該工作：

onLoad in Global ~= (_ andThen ("project server" :: _))
