git 子模块的使用

1. 创建 submoduleA
   创建 submoduleB

2. 初始化上面两个项目的git

3. 在 submoduleB 中添加子模块并且关联到submoduleA
   git submodule add https://github.com/chaconinc/submoduleA

运行 git status

$ git status
On branch master
Your branch is up-to-date with 'origin/master'.

Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    new file:   .gitmodules
    new file:   DbConnector

目录下新增了 .gitmodules文件

4. 克隆含有子模块的项目
   git clone https://github.com/chaconinc/submoduleB

这时候submoduleB>submoduleA文件夹是空的

初始化更新子模块
git submodule init
git submodule update

第二甚至更多次的时候 更新所有子模块

git submodule update --remote

如果子模块下还有子模块
git submodule update --recursive

4. 更多配置

设置之后， git status的时候， 可以看到子模块的更新commit
git config status.submodulesummary 1
git status

 git status
On branch master
Your branch is up to date with 'origin/master'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        modified:   .gitmodules
        modified:   submoduleA (new commits)

Submodules changed but not updated:

* submoduleA b035a71...c67058d (2):
  > feat: xx

no changes added to commit (use "git add" and/or "git commit -a")

配置更新子模块的分支

git config -f .gitmodules submodules.submoduleA.branch master

.gitmodules

[submodule "submoduleA"]
    path = submoduleA
    url = https://github.com/zgbbiao/submoduleA.git
[submodules "submoduleA"]
    branch = master
