1、在码云创建项目

在码云上按照提示创建项目

2、本地git添加远程库与本地库的关联

git init
git remote add origin https://gitee.com/xidianzxm/mybatisplus.git
or
git remote add origin git@gitee.com:xidianzxm/mybatisplus.git

3、本地提交

git add .
git commit -m "first commit"

4、拉取远程更新

git fetch

5、更新与本地合并

MacBookPro:mybatisplus zhangxm$ git merge origin/master
fatal: 拒绝合并无关的历史
MacBookPro:mybatisplus zhangxm$  git pull origin master --allow-unrelated-histories 
来自 gitee.com:xidianzxm/mybatisplus
 * branch            master     -> FETCH_HEAD
