Scalatra的單機部署不能創建裝配

當我運行「集結號」的命令由Scalatra的文檔作爲instrcuted（http://www.scalatra.org/2.2/guides/deployment/standalone.html）我得到以下錯誤：Scalatra的單機部署不能創建裝配

這是什麼意思，以及怎麼了被修復？

這裏是合併策略被設置爲我的第一個構建文件：

    val ScalatraVersion = "2.2.1"

    jarName in assembly := "scalatra_atmosphere_demo.jar" 



     lazy val project = Project (

     file("."), 

     settings = Defaults.defaultSettings ++ ScalatraPlugin.scalatraWithJRebel ++ scalateSettings ++ assemblySettings ++ Seq(

       Seq(

        Binding("context", "_root_.org.scalatra.scalate.ScalatraRenderContext", importMembers = true, isImplicit = true) 

       ), /* add extra bindings here */ 

       Some("templates") 

      ) 

      ) 

      }, 

      resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/" 

     ) 

    )

首先，在build.scala你不必讓每個行之間空白行。

其次，SBT-組件的設置必須的項目設置的一部分，所以你必須在您Seq(...)的某處。

三，你的合併策略是行不通的，因爲類型是不正確的，你通常不能先挑選了一切。你應該嘗試類似：

Seq(
    organization := Organization, 
    name := Name, 
    .... 

    jarName in assembly := "scalatra_atmosphere_demo.jar", 
    mergeStrategy in assembly <<= (mergeStrategy in assembly) { (old) => 
    { 
     case PathList(xs @ _*) if xs.last endsWith ".html" => MergeStrategy.first 
     case x => old(x) 
    } 
    } 
)
