git 迁移项目中某个目录到一个已经存在的项目

需求

需求,一个多模块的项目要将其中的部分功能迁移到一个新的项目,带着提交记录一起迁移,新项目git 已经存在部分目录。核心需求就是想带着git 提交记录一起去。

步骤

1、克隆到自己本地

git clone git@github.com:mybatis/spring-boot-starter.git

目录list

$ ls -l | grep  'mybatis'
drwxr-xr-x   6 wangji  staff    192 12 20 23:09 mybatis-spring-boot-autoconfigure
drwxr-xr-x  17 wangji  staff    544 12 20 23:09 mybatis-spring-boot-samples
drwxr-xr-x   5 wangji  staff    160 12 20 23:09 mybatis-spring-boot-starter
drwxr-xr-x   5 wangji  staff    160 12 20 23:09 mybatis-spring-boot-starter-test
drwxr-xr-x   6 wangji  staff    192 12 20 23:09 mybatis-spring-boot-test-autoconfigure

2、过滤自己需求的目录

以 mybatis-spring-boot-samples 为例子

$ git filter-branch -f --subdirectory-filter mybatis-spring-boot-samples
Rewrite ecdbae5e25b2f74b53a7c6ac33bb3acdd4b77a36 (193/209) (11 seconds passed, remaining 0 predicted)
Ref 'refs/heads/master' was rewritten

目录list,这里其他的都被删除了 mybatis-spring-boot-samples 作为主目录了

$ ls -l | grep  'mybatis'
drwxr-xr-x  6 wangji  staff   192 12 20 23:13 mybatis-spring-boot-sample-annotation
drwxr-xr-x  6 wangji  staff   192 12 20 23:13 mybatis-spring-boot-sample-freemarker
drwxr-xr-x  6 wangji  staff   192 12 20 23:13 mybatis-spring-boot-sample-freemarker-legacy
drwxr-xr-x  6 wangji  staff   192 12 20 23:13 mybatis-spring-boot-sample-groovy
drwxr-xr-x  6 wangji  staff   192 12 20 23:13 mybatis-spring-boot-sample-kotlin
drwxr-xr-x  6 wangji  staff   192 12 20 23:13 mybatis-spring-boot-sample-thymeleaf
drwxr-xr-x  6 wangji  staff   192 12 20 23:13 mybatis-spring-boot-sample-velocity
drwxr-xr-x  6 wangji  staff   192 12 20 23:13 mybatis-spring-boot-sample-velocity-legacy
drwxr-xr-x  6 wangji  staff   192 12 20 23:13 mybatis-spring-boot-sample-war
drwxr-xr-x  6 wangji  staff   192 12 20 23:13 mybatis-spring-boot-sample-web
drwxr-xr-x  6 wangji  staff   192 12 20 23:13 mybatis-spring-boot-sample-xml

3、推送到目标git 地址目标仓库

从当前master分支推送一个到远程的新项目origin/test 分支

git push git@git@github.com:xxxPerson/test.git/test.git master:origin/test

日志记录

$ git push git@git@github.com:xxxPerson/test.git/test.git master:origin/test
