SBT聚合子项目

Question

给定一个项目结构：

rootProject
  aggregatingSubProject
    subA
    subB
  subC

如何在不手动指定的情况下为aggregatingSubProject 及其所有聚合项目运行package 任务？

到目前为止，我只能在 rootProject 中执行 package 时构建 subA 和 subB - 无论我是否将 .aggregate(subA, subB) 放在 aggregatingProject 的 build.sbt 中。

我需要rootProject 来定义构建的通用设置，并且我想在单个构建中构建多个项目（一些聚合其他项目，如aggregatingSubProject 所做的）。

编辑：我需要在不指定根 build.sbt 中的所有子子项目的情况下执行此操作。我想在 aggregatingSubProject/build.sbt 中定义 subA 和 subB。

使用 sbt 0.13.16。

Answer 1

鉴于此build.sbt:

val rootProject = project in file(".")
val aggregatingSubProject = project
val subC = project

这个在aggregatingSubProject/build.sbt:

aggregateProjects(subA, subB)

val subA = project
val subB = project

您可以运行aggregatingSubProject/package 并获取：
