Scala + Eclipse + Casbah = object mongodb不是软件包com的成员

Question

我用的是喷雾剂加卡巴和沙龙。当我导入casbah进口时我会得到这个错误，

import com.mongodb.casbah.Imports._

object mongodb is not a member of package com

但是，sbt可以成功编译任何警告。我的build.sbt看起来

scalaVersion  := "2.10.3"

scalacOptions := Seq("-unchecked", "-deprecation", "-encoding", "utf8")

resolvers ++= Seq(
  "spray repo" at "http://repo.spray.io/",
   "Sonatype releases" at "https://oss.sonatype.org/content/repositories/releases"
)

libraryDependencies ++= {
  val akkaV = "2.2.3"
  val sprayV = "1.2.0"
  Seq(
    "io.spray"            %   "spray-can"     % sprayV,
    "io.spray"            %   "spray-routing" % sprayV,
    "io.spray"            %   "spray-testkit" % sprayV  % "test",
    "com.typesafe.akka"   %%  "akka-actor"    % akkaV,
    "com.typesafe.akka"   %%  "akka-testkit"  % akkaV   % "test",
    "org.specs2"          %%  "specs2-core"   % "2.3.7" % "test",
    "org.mongodb"         %%  "casbah"        % "2.7.0-RC0",
    "com.novus"           %%  "salat"         % "1.9.5"
  )
}

知道如何说服Eclipse找到这个包吗？

Answer 1

最后，我编辑了原始的模板喷射项目，将casbah和salat依赖项添加到build.sbt，运行sbt，并手动将新的.classpath文件复制到导入的eclipse项目中。

Answer 2

使用sbteclipse插件配置eclipse项目：https://github.com/typesafehub/sbteclipse

Answer 3

Salat使用Casbah 2.6.4，并将其作为一个dependency1列出，因此可能会出现一个问题，试图有两个不同的版本。尝试将其更改为2.6.4或删除它，并允许salat隐式声明它。
