问题描述
从某些sbt文档(例如范围)，我看到:
From some sbt document(e.g. scopes), I see:
{.}/*:name
表示entire build中的name(使用name in ThisBuild进行定义)
means name in entire build(use name in ThisBuild to define it)
*/*:name
表示global project中的name(使用name in Global进行定义)
means name in global project(use name in Global to define it)
(PS:我忽略了配置部分*:)
(PS: I ignored the config part *:)
但是，我仍然不知道它们之间有什么区别，它们在我看来完全一样.
But, I still don't know what is the difference between them, they seem exactly the same to me.
我有什么可以做的而不是另一件事?
Is there any thing I can do with one rather than another one?
推荐答案
您在ThisBuild中指定的任何版本都将应用于您构建中的所有项目，从而覆盖可能在Global中定义的任何内容.
Whatever version you specified in ThisBuild will be applied to all projects in your build, overriding anything that was possibly defined in Global.
例如:键版本"
For example: Key "version"
对于全局范围，它是在Defaults.scala中定义的，其值为"0.1-SNAPSHOT".
For Global scope it was defined in Defaults.scala with value "0.1-SNAPSHOT".
对于此版本中的项目，您可能需要使用以下内容覆盖:
For your projects in this build you might want to overwrite that with:
version in ThisBuild := "3.0.1"
因此，由于[{.}/*:version]的优先级高于[*/*:version]，因此，只要在项目中获得版本"，便会获取"3.0.1"而不是"0.1-SNAPSHOT"
So, because [{.}/*:version] has precedence over [*/*:version], whenever you get "version" in your projects, you fetch "3.0.1" instead of "0.1-SNAPSHOT".
这在很大程度上解释了区别以及如何使用一个而不是另一个.
This pretty much explains the difference and how you could use one and not the other.
