sbt 中的项目文件夹 [英] project folder in sbt

问题描述

我知道在 sbt 项目中，sbt 会生成一个名为 project 的文件夹，其中包含 build.properties 和 plugins.sbt.现在，如果我有一个包含多个子项目的项目，我应该在根项目中只有一个名为 project 的文件夹还是每个子项目名为 project 的不同文件夹?

I understand that in an sbt project, sbt generates a folder called project containing build.properties and plugins.sbt. Now if I have one project that has multi subprojects, should I have only one folder called project in the root project or different folders named project foreach subproject?

推荐答案

你应该只有一个 project 文件夹.您可以在 Multi-项目在 sbt 文档中构建.

You should have only one project folder. You can read about it at Multi-project builds in sbt documentation.

以下面的sbt为例:

name := "new_proj"
version := "0.1"
scalaVersion := "2.13.4"

lazy val root = (project in file("."))
  .aggregate(util, core)

lazy val util = (project in file("util"))

lazy val core = (project in file("core"))

你应该有这样的结构:

new_proj
  |- build.sbt
  |- project
    |- build.properties
  |- core
    |- src
      |- main
        |- scala
  |- util
    |- src
      |- main
        |- scala
