Playframework 无法使用sbt创建Play framework web应用程序？

我使用sbt创建了一个新的播放应用程序myFirstApp。我在myFirstApp文件夹中有一个

build.sbt

，在

myFirstApp/project

文件夹中有一个

plugins.sbt

但是，我在从myFirstApp执行

sbt

时遇到以下错误

~/ScalaWorkspace/myFirstApp/build.sbt:7: error: not found: value playScalaSettings
playScalaSettings
^
[error] Type error in expression
Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore? i
[warn] Ignoring load failure: no project loaded.

我如何解决这个问题

更新1:获取此错误：

这是我第一次以

sbt

为中心的游戏开发，如果解决方案不符合可接受的质量标准，请耐心等待

我按照文档中的创建一个新的应用程序而没有安装Play一节进行操作，最后得到了以下文件

build.sbt

如本文档所述

import play.Project._

name := "My first application"

version := "1.0"

playScalaSettings

然后我创建了

project/build.properties

，因为这是一种推荐的方法，可以复制构建—sbt的版本是已知的，并且是固定的

sbt.version=0.13.0

我将

project/plugins.sbt

修改如下：

// Typesafe snapshots
resolvers += "Typesafe Snapshots" at "http://repo.typesafe.com/typesafe/snapshots/"

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

// Use the Play sbt plugin for Play projects
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.2.0-RC2")

有了项目中的文件，我可以执行

sbt

，并得到项目的提示

jacek:~/sandbox/myFirstApp
$ sbt
[info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins
[info] Loading project definition from /Users/jacek/sandbox/myFirstApp/project

--- (Running the application from SBT, auto-reloading is enabled) ---

我注意到你使用play#…2.9.2；。。。因此它与我在回复中提供的内容不同-您应该在

addSbtPlugin

中使用

com.typesafe.play

。版本

2.9.2

也是一个警告标志，表明您正在使用另一个版本的Scala-请确保您使用sbt 0.13.0.Jacek，仔细检查后，我注意到我使用的是sbt 0.12.3。在使用sbt 0.13.0进行尝试时，它成功了。谢谢。
