scala - 无法获得 spray-json 依赖项以在游戏项目中工作

Question

我花了无数个小时试图将 spray json 作为依赖项包含在我基于 scala 2.10 构建的 play 项目中。

有人可以为这个项目文件中使用的确切魔法咒语提供明确的解释吗？!!!!!

构建.scala:

import sbt._
import Keys._
import play.Project._

object ApplicationBuild extends Build {
    val appName         = "linscot"
    val appVersion      = "1.0"

    val appDependencies = Seq(
      jdbc,
      anorm,
      "mysql" % "mysql-connector-java" % "5.1.18",
      "com.cloudphysics" % "jerkson_2.10" % "0.6.3",

      //"cc.spray.json" % "spray-json_2.9.1" %"1.0.1"
      "io.spray" %  "spray-json_2.10.1" % "1.2.5"
    )


    val main = play.Project(appName, appVersion, appDependencies).settings(   
      // Add your own project settings here   

        //libraryDependencies += "io.spray" %%  "spray-json" % "1.2.5"


    )
}

得到这个:

Answer 1

spray-json 依赖的格式是:

"io.spray" %%  "spray-json" % "1.2.5"

使用 %% 确保您获得适合您正在使用的 Scala 版本的正确版本。

Spray 不使用默认存储库之一来分发库，因此您还必须指定那个存储库。然后设置变成:

val main = play.Project(appName, appVersion, appDependencies).settings(   
    resolvers += "spray" at "http://repo.spray.io/",
    libraryDependencies += "io.spray" %%  "spray-json" % "1.2.5"
)
