Question

我的目录结构：

-build.sbt
-src
--main
---scala
----MongoConnect.scala
-lib

我的build.sbt：

name := "mongodb-experiments"

version := "0.1"

libraryDependencies ++= Seq(
  "com.mongodb.casbah" %% "casbah" % "3.0.0-SNAPSHOT"
)

resolvers += "Sonatype OSS Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots"

我的MongoConnect.scala计划：

import com.mongodb.casbah.Imports._
object MongoConnect{
  def main(args: Array[String]){
    println("Hello Mongo")
  }
}

为什么sbt compile会导致

object casbah不是com.mongodb包的成员

sbt compile

Answer 1

为什么使用快照存储库和旧版本的casbah？

libraryDependencies ++= Seq(
  "org.mongodb" %% "casbah" % "2.4.1"
)

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

%%登录依赖项将选择在sbt scala版本中配置

对于3.x版本，有一个里程碑

libraryDependencies ++= Seq(
      "org.mongodb" %% "casbah" % "3.0.0-M2"
    )

正如我记得在3.x中导入应该改为：

import com.mongodb.casbah._

Answer 2

将build.sbt文件修改为：

name := "mongodb-experiments"

version := "0.1"

libraryDependencies ++= Seq(
  "com.mongodb.casbah" % "casbah_2.9.0" % "2.2.0-SNAPSHOT"
)

resolvers += "Sonatype OSS Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots"

出于某种原因，3.0.0不起作用。

sbt compile产生“对象casbah不是包com.mongodb的成员”
