git - 在子模块中添加一个 git 子模块(嵌套子模块)

Question

As described in this Question

是否有可能一个 git 子模块由多个其他 git 子模块组成，并且 super git repo 可以获取每个子模块的内容？

作者假设了一个像这样的 git 子模块层次结构:

• repo 1
  • 子模块 xyz1
  • 子模块xyz2
• repo 协议(protocol)2
  • 子模块 repo1

这个问题是关于在子模块中嵌套子模块的可能性:

• repo 1
  • 子模块a
    • 子模块ab
    • 子模块ac

.gitmodules 的真实例子应该是这样的:

[submodule "Source/V8"]
    path = Source/V8
    url = https://chromium.googlesource.com/v8/v8.git
[submodule "Source/V8/build/gyp"]
    path = Source/V8/build/gyp
    url =  https://chromium.googlesource.com/external/gyp
[submodule "Source/V8/third_party/cygwin"]
    path = Source/V8/third_party/cygwin
    url = https://chromium.googlesource.com/chromium/deps/cygwin
[submodule "Source/V8/third_party/python_26"]
    path = Source/V8/third_party/python_26
    url = https://chromium.googlesource.com/chromium/deps/python_26
[submodule "Source/V8/third_party/icu"]
    path = Source/V8/third_party/icu
    url = https://chromium.googlesource.com/chromium/deps/icu52
[submodule "Source/V8/testing/gtest"]
    path = Source/V8/testing/gtest
    url = https://chromium.googlesource.com/chromium/testing/gtest
[submodule "Source/V8/testing/gmock"]
    path = Source/V8/testing/gmock
    url = https://chromium.googlesource.com/chromium/testing/gtest

注意子模块的路径是嵌套的:

• 来源/V8
  • 源码/V8/build/gyp
  • 来源/V8/third_party/cygwin

我尝试了以下示例但没有成功:

 git submodule add https://chromium.googlesource.com/v8/v8.git   
 Source/V8
 git submodule add https://chromium.googlesource.com/external/gyp 
 Source/V8/build/gyp 

结果:

 The following path is ignored by one of your .gitignore files:
 Source/V8/build/gyp
 Use -f if you really want to add it.

使用 git submodule add -f 结果:

Cloning into 'Source/V8/build/gyp'...
remote: Sending approximately 10.28 MiB ...
remote: Total 16486 (delta 10444), reused 16486 (delta 10444)
Receiving objects: 100% (16486/16486), 10.28 MiB | 2.07 MiB/s, done.

Checking connectivity... done.
fatal: Pathspec 'Source/V8/build/gyp' is in submodule 'Source/V8'
Failed to add submodule 'Source/V8/build/gyp'

如果可以实现这种情况，请现在告诉我。

更新:注意这个问题是关于创建子模块结构，而不是初始化它。

简短回答:是的。 归根结底，子模块是一个模块，但在另一个模块内。

这意味着如果您设置一个带有子模块的父仓库。您可以进入该子模块并在其中设置另一个模块。 这样，父存储库将看到您的子模块内部有一些更改，但不会看到其中有另一个子模块。
