当我添加带有另一个 git 分支的文件夹作为项目的子文件夹时，为什么会有 sbt 异常？
Why is there a sbt exception there, when I have added the folder with another git branch as a subfolder of the project?
为了像另一个项目开发人员已经完成的那样设置项目，我这样做
- 克隆根项目 repo 和 switch/checkout 开发文件夹。它在相应的文件夹中包含一些名为 core 和 deps 的项目。
此根的 build.sbt 包含对某些 sbt 项目的提及：
lazy val industry = (project in file("industry"))
它没有指向根文件夹中的实际文件夹
- 创建
industry 文件夹，cd 到它，再次检出项目并 switch/checkout 到特定分支（例如，industry-dev）
所以现在提到的项目文件夹有项目本身，它承载了自己的 build.sbt 和存在于相应文件夹中的其他人员。我们必须这样设置，因为 industry-dev 基于 dev 的 类，作为核心 类，我们需要同时观察它们, 不将单个项目从一个分支切换到另一个分支
在根目录下尝试执行
sbt core/clean
我收到以下消息的错误：

那里的核心问题是什么？
出现此异常的原因是分支的误用，每个分支都包含预期的 build.sbt。事实上，子文件夹分支与 roo 相同，因此子项目 build.sbt 实际上与根项目相同 build.sbt
因此，如果您遇到这种情况，请检查子项目的代码是否符合您的预期。
为了像另一个项目开发人员已经完成的那样设置项目，我这样做
- 克隆根项目 repo 和 switch/checkout 开发文件夹。它在相应的文件夹中包含一些名为 core 和 deps 的项目。
build.sbt 包含对某些 sbt 项目的提及：
lazy val industry = (project in file("industry"))

出现此异常的原因是分支的误用，每个分支都包含预期的 build.sbt。事实上，子文件夹分支与 roo 相同，因此子项目 build.sbt 实际上与根项目相同 build.sbt
因此，如果您遇到这种情况，请检查子项目的代码是否符合您的预期。
