Writing
当需要将内容写入控制台时，你始终可以使用 JDK 的 System.out，然后直接进入 JDK 自身的流。另一种推荐的方法是使用 JLine 的 Terminal 并从那里获取 writer 实例。
When something needs to get written into your console you can always
use JDK’s System.out which then goes directly into JDK’s own streams.
Other recommended way is to use JLine’s Terminal and get writer
instance from there.
如果使用目标端点，即 consumer，则不希望返回任何内容，因为 CommandContext 包含对 Terminal 的引用，并且可以从那里访问写入器。
If using target endpoints, i.e. consumer which is not expected
to return anything given CommandContext contains reference to
Terminal and writer can be accessed from there.
