含分支子模块的Git仓库递归克隆报错求助

我用Git子模块+分支作为临时包管理系统，为Godot引擎开发插件——通过GitHub Action把插件发布到仓库的release分支，再将该分支作为其他插件/项目的子模块使用。

现在遇到嵌套子模块的问题，依赖结构如下：

FixedGodotVolatilePhysicsRollback
|-> FracturalCommons
'-> FixedGodotVolatilePhysics
   '-> FracturalCommons

执行递归克隆命令时出错：

拉取的是release分支，该分支不含.gitmodules文件，仅包含插件文件夹，理论上不需要递归FixedGodotVolatilePhysics的子模块，请问如何避免这个错误？

• 手动初始化顶层子模块，跳过递归嵌套
  先克隆主仓库，再单独初始化直接依赖的子模块，不触发嵌套递归：

  git clone https://github.com/Fractural/GodotFixedVolatilePhysicsRollback.git
  git submodule update --init
  

  此操作只会处理主仓库.gitmodules中定义的直接子模块，不会深入嵌套子模块。

• 修改主仓库子模块配置，禁用嵌套递归
  在主仓库的.gitmodules文件中，给FixedGodotVolatilePhysics子模块添加ignore = all配置，让Git忽略该子模块内部的嵌套依赖：

  [submodule "addons/GodotFixedVolatilePhysics"]
      path = addons/GodotFixedVolatilePhysics
      url = https://github.com/Fractural/GodotFixedVolatilePhysics.git
      ignore = all
  

  提交该修改到主仓库后，执行git clone --recurse-submodules就不会尝试递归该子模块的内部内容。

• 克隆时指定仅递归特定子模块
  明确指定需要递归的直接子模块路径，跳过可能引发问题的子模块：

  git clone --recurse-submodules="addons/FracturalCommons,addons/GodotRollbackNetcodeMono" https://github.com/Fractural/GodotFixedVolatilePhysicsRollback.git
  

  后续可单独处理FixedGodotVolatilePhysics子模块，无需递归它的内部依赖。
