如何设置子模块，以便git clone --recursive始终掌握子模块的权限

问题描述

我已经引用了以下内容: Git子模块头'reference不是树的错误

I've reference this: Git submodule head 'reference is not a tree' error

这是 git子模块跟踪最新

可能我的问题略有不同.(我假设它是相同的，但没有做正确的事...)

Possibly my problem is slightly different. (I'm assuming its the same but not doing something right...)

我希望自己的git设置能够运行:

I want my git setup such that if I run:

git clone -b master --recursive /path/to/main/repo.git

子模块 应该始终针对主"进行克隆

否则，在许多情况下，所引用的提交不存在(子模块的分支)或已过时"，从而导致克隆失败并显示错误:

Otherwise, in many cases the referenced commit doesn't exist (The branch of the submodule) or are "out of date" causing the clone to fail with error:

fatal: reference is not a tree

我试图设置主存储库以使用子模块主模块:

I've tried to setup the main repository to take the submodule master:

git submodule add -b master /path/to/submodule.git

但是在克隆主仓库时:

git clone -b master --recursive /path/to/main/repo.git

所引用的子模块提交不存在(未按预期使用master)

The submodule commit referenced doesn't exist (not taking master as expected)

推荐答案

由于子模块从未针对分支签出.
总是在 gitlink ()

As submodule is never checked out against a branch.
It is always checked out at the SHA1 recorded by the gitlink (special entry in the index)

您可以做的是:

• 确保子模块设置为遵循 master 分支
  请参阅"如何使现有子模块跟踪分支"
• 执行 git子模块更新--remote --recursive ，以确保每个子模块均可获取并根据其各自的 master 分支进行更新.

• making sure the submodule is set to follow the master branch
  See "How to make an existing submodule track a branch"
• do a git submodule update --remote --recursive to make sure each submodule fetch and update themselves against their respective master branch.
