“玩依赖”从何而来？

Question

在另一个问题Why is Eclipse not able to resolve Guice import in Play 2.2.x application?我了解了play dependencies命令。

[play-new-app] $ dependencies
[info] :: delivering :: play-new-app#play-new-app_2.11;1.0-SNAPSHOT :: 1.0-SNAPSHOT :: integration :: Thu Oct 23 23:56:30 CEST 2014
[info]  delivering ivy file to /Users/jacek/sandbox/play-new-app/target/scala-2.11/ivy-1.0-SNAPSHOT.xml

Here are the resolved dependencies of your application:

+------------------------------------------------------------+------------------------------------------------------------+--------------------------------------------+
| Module                                                     | Required by                                                | Note                                       |
+------------------------------------------------------------+------------------------------------------------------------+--------------------------------------------+
| com.typesafe.play:play-ws_2.11:2.3.5                       | play-new-app:play-new-app_2.11:1.0-SNAPSHOT                | As play-ws_2.11-2.3.5.jar                  |
...

我似乎无法在 sbt/activator 会话中通过 help 或 inspect 对其进行检查。

[play-new-app] $ inspect dependencies
[error] Not a valid project ID: dependencies
[error] Expected ':' (if selecting a configuration)
[error] Not a valid key: dependencies (similar: ivy-dependencies, all-dependencies, rpm-dependencies)
[error] inspect dependencies
[error]                     ^

命令从何而来？是否支持（因为命令的最后一个跟踪位于 Play 1.2.1's documentation 中）？我在哪里可以找到最新版本 2.3.5 的文档中有关该命令的页面？

Answer 1

dependencies 和h2-browser、license 和classpath 一样是一个命令。它们都在 PlayCommands 和 dependencies 中定义，并可通过 Play 插件用于任何 Play 项目。

inspect 和 help 似乎不适用于 sbt 中的命令。
