我已按照此文档使用 sbt 创建了一个新的 Play 应用程序 myFirstApp。我有一个build.sbtmyFirstApp 文件夹和一个plugins.sbtinmyFirstApp/project文件夹。

但是，我在sbt从 myFirstApp 执行时收到以下错误，

~/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.

我该如何解决这个问题？

更新1：得到这个错误：

那是我的第一个sbt以 Play 为中心的开发，如果解决方案不符合可接受的质量标准，请多多包涵。

我按照文档创建新应用程序中未安装 Play的情况下创建新应用程序部分进行操作，最后得到以下文件。

build.sbt如文档中所述。

import play.Project._

name := "My first application"

version := "1.0"

playScalaSettings

然后我创建project/build.properties了它，因为它是具有可重复构建的推荐方法 - sbt 的版本是已知和固定的。

sbt.version=0.13.0

我修改project/plugins.sbt为如下：

// 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")

使用项目中的文件，我可以执行sbt并获得项目的提示。

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

...lots of [SUCCESSFUL ]'s
