设想:
我现在有以下设置，也可以在GitHub上使用:https://github.com/ComFreek/sbt-multi-project-question
| - .git
|
| - projectA
| | - src
| | - build.sbt
|
| - projectB (Git submodule)
| | - src
| | | - build.sbt
| | | - project
| | | - project.sbt
| | | - ...
在
projectA/build.sbt中尝试过:unmanagedBase := baseDirectory.value / ".." / "projectB" / "deploy" / "lib"
lazy val projectB = RootProject(file("../projectB/src/project"))
lazy val projectA = Project(id = "projectA", base = file(".")).settings(
name := "projectA",
version := "0.1",
scalaVersion := "2.12.8",
scalacOptions in ThisBuild ++= Seq("-unchecked", "-deprecation")
).dependsOn(projectB)
但是，似乎
projectB/src/build.sbt 使用了放入 projectB/deploy/lib 中的非托管库，当从projectA的范围内运行sbt compile时，即使设置了unmanagedBase属性，也无法找到该库。具体而言，您可以按照以下方式重现它:

但是，以下工作原理:
projectB/src打开一个SBT shell。 compile请注意，这在我的计算机上花费了大约12分钟的时间，并且会输出很多警告，但不会出现错误。 研究。 有一些资源说明了如何在子项目之间共享非托管库(例如下面的1和2)，但是似乎没有一个资源面临build设置(不仅是代码!)还取决于那些非托管库的问题。
最佳答案
我设法通过以下更改来编译项目。
首先，在尝试编译projectB @ b558245修订版时遇到编译错误，该错误在您的GitHub项目中被引用。我检查了最新的标签v15.0.0，并对其进行了编译。
其次，在projectA/build.sbt中，projectB应该定义为
lazy val projectB = RootProject(file("../projectB/src"))
../projectB/src/project是用于构建projectB的构建器项目。它需要scala编译器和sbt中的内容，因此会产生尝试直接编译时看到的错误。第三，
projectB无法编译为projectA的依赖项。这是因为，用于引用Utils布局的projectB/src/project/Utils.scala对象(在projectB中)是用错误的目录(../projectA)初始化的object Utils {
/** MMT root directory */
val root = File("..").canonical // Got the wrong directory when compiled with projectA
因此，我们必须对
Utils.scala及其依赖项进行一些修改，以确保它始终找到projectB的正确位置。这是projectB的补丁程序，可从projectA进行编译。可能不是最好的解决方案，但是它可以在我的笔记本电脑上使用。diff --git a/src/build.sbt b/src/build.sbt
