build.sbt：导入“项目”对象的位置是什么？

Question

在build.sbt中，我们可以lazy val root = (project in file("."))。

我知道sbt做了一些导入，但我在API文档中找不到我们如何直接使用'project'对象。

Answer 1

This is written in the documentation:

import sbt._
import Process._
import Keys._

If you auto-complete project in IntelliJ IDEA, it brings you to trait ProjectExtra. This is available to due the fact that the package object sbt mixes in this trait. This is a bit hidden in the API docs. But it's clear from the source code (and here).
