Playframework 如何将播放json依赖项添加到项目中？

我想向sbt项目添加

播放json

依赖项

我在

项目/plugins.sbt

中添加了类型安全存储库：

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

然后我在

Build.scala

中添加了

play json

依赖项，如下所示：

libraryDependencies += "com.typesafe.play" % "play-json_2.10" % "2.2.1"

[warn]  module not found: com.typesafe.play#play-json_2.10;2.2.1
[warn] ==== local: tried
[warn]   /home/tminglei/.ivy2/local/com.typesafe.play/play-json_2.10/2.2.1/ivys/ivy.xml
[warn] ==== sonatype-snapshots: tried
[warn]   https://oss.sonatype.org/content/repositories/snapshots/com/typesafe/play/play-json_2.10/2.2.1/play-json_2.10-2.2.1.pom
[warn] ==== public: tried
[warn]   http://repo1.maven.org/maven2/com/typesafe/play/play-json_2.10/2.2.1/play-json_2.10-2.2.1.pom
[info] Resolving org.scala-tools.testing#test-interface;0.5 ...
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::
[warn]  ::          UNRESOLVED DEPENDENCIES         ::
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::
[warn]  :: com.typesafe.play#play-json_2.10;2.2.1: not found
[warn]  ::::::::::::::::::::::::::::::::::::::::::::::

这样，我得到了如下错误：

libraryDependencies += "com.typesafe.play" % "play-json_2.10" % "2.2.1"

[warn]  module not found: com.typesafe.play#play-json_2.10;2.2.1

如何排序？

看起来它没有使用您定义的解析器。这在sbt 13中适用于我：

import sbt._
import Keys._

object Build extends sbt.Build {

  lazy val playjsondep = Project(
    id = "play-json-dep",
    base = file("."),
    settings = Project.defaultSettings ++ Seq(
      name := "play-json-dep",
      organization := "ee.so",
      version := "0.1-SNAPSHOT",
      scalaVersion := "2.10.2",
      resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/",
      libraryDependencies += "com.typesafe.play" %% "play-json" % "2.2.1"
    )
  )
}

---

由于依赖项不是插件，因此您应该只在项目的主目录中将

resolvers

设置添加到

build.sbt

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

---

对于这样一个简单的配置，您真的不需要

project/*.scala

文件。

文件

plugins.sbt

？它的路径是：/[project\u root]/project/plugins.sbt
