idea项目代码上传git 命令操作 版本回退 warning: LF will be replaced by CRLF in .idea/workspace.xml.

1.项目根目录右键 选择 Git Bash Here

2..初始化 git init

admin@DESKTOP-JQ2K526 MINGW64 /d/workSpaceWork/RSADemo
$ git init
Initialized empty Git repository in D:/workSpaceWork/RSADemo/.git/

3.登录git 新建项目仓库

 

 4.点击进入新建的仓库 复制HTTPS路径git add .

 5.git remote add origin +复制的git项目仓库HTTPS地址

admin@DESKTOP-JQ2K526 MINGW64 /d/workSpaceWork/RSADemo (master)
$ git remote add origin https://gitee.com/haha_1992/rsademo.git

6.git pull origin master 取回 origin/master 分支，再与本地的 brantest 分支合并

admin@DESKTOP-JQ2K526 MINGW64 /d/workSpaceWork/RSADemo (master)
$ git pull origin master

7. git add . （添加该目录下所有文件）将文件保存到缓存区   注意后面是有"."的 

admin@DESKTOP-JQ2K526 MINGW64 /d/workSpaceWork/RSADemo (master)
$ git add .

7.1.如果出现如下报错：是由于缓存

warning: LF will be replaced by CRLF in .idea/dataSources/a2ed9618-2b08-45d1-b3c2-af78d6697818.xml.
The file will have its original line endings in your working directory
warning: LF will be replaced by CRLF in .idea/dataSources/a2ed9618-2b08-45d1-b3c2-af78d6697818/storage_v2/_src_/schema/information_schema.FNRwLQ.meta.
The file will have its original line endings in your working directory
warning: LF will be replaced by CRLF in .idea/workspace.xml.
The file will have its original line endings in your working directory
warning: LF will be replaced by CRLF in pom.xml.
The file will have its original line endings in your working directory

7.2.解决办法：(删除缓存)  git rm -r -f --cached ./

admin@DESKTOP-JQ2K526 MINGW64 /d/workSpaceWork/RSADemo (master)
$ git rm -r -f --cached ./

8. git commit -m "first commit"  第一次提交到本地仓库

admin@DESKTOP-JQ2K526 MINGW64 /d/workSpaceWork/RSADemo (master)
$ git commit -m "first commit"

9.git push   第一次提交失败

admin@DESKTOP-JQ2K526 MINGW64 /d/workSpaceWork/RSADemo
$ git push

这是因为本地的分支没有和远程分支建立联系，需要执行以下代码就可以正常push了：

将本地仓库推送到远程仓库 

9.1 git push --set-upstream origin master（master可以根据子的需要自定义，就是当前分支在远程分支对应的名称）

admin@DESKTOP-JQ2K526 MINGW64 /d/workSpaceWork/RSADemo (master)
$ git push --set-upstream origin master

第二次提交 执行顺序

 如果有修改的文件继续执行添加文件到缓存去 git add . 注意后面是有"."的 

1.$ git add .  添加文件到缓存

2.$ git commit -m "第二次提交" 提交文件到本地仓库

3.$ git push  本地仓库提交到远程仓库

项目版本回退

1. git log 查看提交历史的 commit 版本号

admin@DESKTOP-JQ2K526 MINGW64 /d/workSpaceWork/RSADemo (master)
