如何在 sbt shell 中设置子项目(不使用项目命令)?

问题描述

在 sbt shell 中如何设置子项目的设置?

In sbt shell how do I set a setting for a subproject?

我知道我可以project subproject然后set key := value，但我不想一直切换项目.理想情况下，与以下内容没有太大区别:

I know I can project subproject then set key := value, but I don't want to have to keep switching projects. Ideally something not too different from:

set key in subproject := value

推荐答案

我觉得问题是你在 build.sbt 中定义了你的项目，而它们在 sbt 中似乎不可见安慰.至少在 sbt 的当前版本中 - 请参阅 this issue 和 这个问题实际上在几天前才修复(！)

I think the problem is that you have defined your projects in build.sbt, and they seem not to be visible in the sbt console. At least in the current version of sbt - see this issue and this issue that were in fact fixed just a couple of days ago (!)

我找到了两种方法来克服这个限制.

I have found two ways to overcome this limitation.

set version in "projectId" := "some-version"

在 project/Build.scala 文件中创建完整的构建定义

使用以下构建定义文件 build/Build.scala:

import sbt._
import Keys._

object Build extends Build {
  lazy val projectA, projectB = project
}

你应该可以在 projectA 中执行 set version :="1.42-SNAPSHOT 并达到预期的效果.

you should be fine to execute set version in projectA := "1.42-SNAPSHOT with the expected effect.

此外，您可以在 build.sbt 中为每个子模块设置包含项目定义和其余配置的 build/Build.scala.使用 set 会非常好.

Additionally you could just have the build/Build.scala containing the project definition and rest of the configuration have in build.sbt for each submodule. It'd work perfectly fine with set.
