64. 使用CLI

一旦安装了CLI，就可以通过在命令行输入spring并按Enter来运行它。如果不使用任何参数运行spring，将会展现一个简单的帮助界面：

$ spring
usage: spring [--help] [--version]
       <command> [<args>]

Available commands are:

  run [options] <files> [--] [args]
    Run a spring groovy script

  ... more command help is shown here

你可以输入help获取任何支持命令的详细信息，例如：

$ spring help run
spring run - Run a spring groovy script

usage: spring run [options] <files> [--] [args]

Option                     Description

                             transformations (default: true)
--classpath, -cp           Additional classpath entries
-e, --edit                 Open the file with the default system
                             editor
