Play Framework：找不到安装命令

Question

我正在尝试为play framework 2.1.1安装maven模块，我无法弄清楚为什么“install”命令不可用：

来自项目：

play install maven

[info] Loading project definition from C:\someproject
[info] Set current project to SomeProject(in build file:/C:\someproject)
[error] Not a valid command: install (similar: initialize, inspect, shell)
[error] Expected '/'
[error] Expected ':'
[error] Not a valid key: install (similar: initialize, dist, stage)
[error] install
[error]        ^

从任何目录：

play install maven
       _            _
 _ __ | | __ _ _  _| |
| '_ \| |/ _' | || |_|
|  __/|_|\____|\__ (_)
|_|            |__/ 

play! 2.1.1 (using Java 1.7.0_21 and Scala 2.10.0), http://www.playframework.org


This is not a play application!

Use `play new` to create a new Play application in the current directory,
 or go to an existing application and launch the development console using `play`
.

install命令仅适用于Play 1.x，module directory列出的模块也是如此。有一些modules for 2.1.1。

要在Play 2.x项目中安装模块，您必须在project/Build.scala中将它们添加为依赖项。该模块的自述文件应告诉您如何使其运行。
