一些SBT依赖性被忽略

Question

我使用sbt在项目中包括依赖项，但是我找不到某些依赖关系被随机忽略的原因。即使它们存在于.ivy2/cache目录中，我也试图删除其内容并重试，但我仍然有同样的问题。

我的SBT的版本是0.13.15这是一个示例：

import org.scalatra.sbt._
import org.scalatra.sbt.PluginKeys._
import ScalateKeys._
val ScalatraVersion = "2.4.1"
ScalatraPlugin.scalatraSettings
scalateSettings
organization := "com.*****"
name := "****"
version := "0.1.0-SNAPSHOT"
scalaVersion := "2.10.5"
val sparkVersion = "1.6.0"
resolvers += Classpaths.typesafeReleases
libraryDependencies ++= Seq(
  "org.scalatra" %% "scalatra-json" % ScalatraVersion,
  "org.json4s"   %% "json4s-jackson" % "3.2.11",
  "org.scalatra" %% "scalatra" % ScalatraVersion,
  "org.scalatra" %% "scalatra-scalate" % ScalatraVersion,
  "org.scalatra" %% "scalatra-specs2" % ScalatraVersion % "test",
  "ch.qos.logback" % "logback-classic" % "1.1.5" % "runtime",
  "org.eclipse.jetty" % "jetty-webapp" % "9.2.15.v20160210" % "container",
  "javax.servlet" % "javax.servlet-api" % "3.1.0" % "provided"
)
libraryDependencies += "org.apache.spark" %% "spark-core" % sparkVersion
libraryDependencies += "org.apache.spark" %% "spark-sql" % sparkVersion
libraryDependencies += "org.scalaz" %% "scalaz-core" % "7.2.14"
scalateTemplateConfig in Compile := {
  val base = (sourceDirectory in Compile).value
  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")
    )
  )
}
enablePlugins(JettyPlugin)

在我的示例中，有时scalatra json被忽略，当我重述创建一个新项目时，spark依赖项被忽略

Answer 1

我终于找到了我的问题的解决方案，我的项目必须通过使用sbt eclipse命令通过SBT转换为Eclipse项目。 最初，Scalatra项目是通过SBT使用此命令创建的： sbt new scalatra/scalatra-sbt.g8

诀窍是在开始导入依赖项之前将项目黯然失色。
