推荐答案

本示例中列出的依赖项是您安装 play 时附带的依赖项.版本与您使用的 Play 框架版本相匹配.

The dependencies listed in this example are the ones that are shipped with your installation of play. The versions match the Play framework version you are using.

Play 框架是模块化的，因此您不必在应用程序中使用其所有模块.这就是为什么您必须指定所需的模块.

Play framework is modular so you don't have to use all of its modules in your application. That is why you must specify which modules you want.
