Question

我使用SBT 0.13.0 。

更新结果表明我在项目中使用了SBT 0.12.2 （我使用sbt sbt-version检查并使用{{1}之前）。

使用以下sbt --version SBT似乎无法获取build.sbt插件/依赖项：

sbt-start-script

当我运行version := "0.1" resolvers += "Typesafe Repo" at "http://repo.typesafe.com/typesafe/releases/" scalaVersion := "2.10.2" libraryDependencies ++= Seq( "play" % "play_2.10" % "2.1.0", "org.mongodb" %% "casbah" % "2.6.3", "com.github.nscala-time" %% "nscala-time" % "0.8.0", "org.twitter4j" % "twitter4j-stream" % "3.0.5" ) resolvers += Classpaths.typesafeResolver addSbtPlugin("com.typesafe.sbt" % "sbt-start-script" % "0.10.0")时，我收到以下错误：

sbt clean compile stage

Answer 1

你应该移动

行

addSbtPlugin("com.typesafe.sbt" % "sbt-start-script" % "0.10.0")

进入自己的project/plugins.sbt文件（如插件文档的Details中所述）。这样插件就会被添加到项目安装的插件中（通过addSbtPlugin方法调用）。

在同一文档中，有Consider sbt-native-packager instead部分说：

更通用的native-packager插件可能会在将来取代此插件：https://github.com/sbt/sbt-native-packager

build.sbt 应如下所示（它仅对插件成功运行有效 - 我不检查其他设置，如libraryDependencies）：

import com.typesafe.sbt.SbtStartScript

version := "0.1"

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

scalaVersion := "2.10.2"

libraryDependencies ++= Seq(
  "play" % "play_2.10" % "2.1.0",
  "org.mongodb" %% "casbah" % "2.6.3",
  "com.github.nscala-time" %% "nscala-time" % "0.8.0",
  "org.twitter4j" % "twitter4j-stream" % "3.0.5"
)

seq(SbtStartScript.startScriptForClassesSettings: _*)

在build.sbt和project/plugins.sbt到位的情况下，当您运行sbt shell时，您应该能够为项目生成启动脚本。

Answer 2

Play 2.1.0。

在project/build.properties中使用：

sbt.version=0.12.2

在project/plugins.sbt中使用：

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

addSbtPlugin("play" % "sbt-plugin" % "2.1.0")

在project/Build.scala中使用：

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

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

    val appDependencies = Seq(
        // project dependencies
    )

    val main = play.Project(appName, appVersion, appDependencies).settings(
        // project settings
    )
}

清除您在系统驱动器上可以找到的.ivy2缓存的内容仍然是一个好主意。然后做：

play clean-all
play compile
play ~run

SBT报告com.typesafe.sbt＃sbt-start-script; 0.10.0的未解析依赖项？
