1. Create a project: Create a gitee link

1. Login giteeto create warehouse

2. Give the project a name (the local name should be the same as the remote one)panda

![在这里插入图片描述](https://img-blog.csdnimg.cn/035b3c64249846d79aa7b5bd7b934236.png)

3. Open IDEA to create a project name:panda

`这里因为IDEA版本问题，最低SpingBoot版本就是2.7.12，一会我们更改build.gradle文件即可`

//id 'io.spring.dependency-management' version '1.0.15.RELEASE' 插件作用========
//类似Maven的dependencyManagement方式实现依赖管理
//1、 使用插件的DSL来直接配置依赖项
//2、导入一个或者多个已经存在的Maven bom文件

//
//implementation（会将依赖项添加到编译类路径，并将依赖项打包到构建输出。） 该模块在编译时将该依赖项泄露给其他模块。也就是说，其他模块只有在运行时才能使用该依赖项。
//compileOnly （只会将依赖项添加到编译类路径（也就是说，不会将其添加到构建输出））
//annotationProcessor 如需添加对作为注解处理器的库的依赖，您必须使用 annotationProcessor 配置将其添加到注解处理器的类路径。这是因为，使用此配置可以将编译类路径与注释处理器类路径分开，从而提高构建性能。
//testImplementation    为 test source set 添加依赖
//androidTestImplementation  为 androidTest source set 添加依赖

}

4. Use git.bash to execute commands

New warehouse (use this operation)

git init

git add README.md

git commit -m “first commit”

git remote add origin https://gitee.com/xx/panda.git

git push -u origin master

There is a warehouse (use the following operations)

git remote add origin https://gitee.com/xx/panda.git

git push -u origin master

Precautions

1. git init will initialize a .git directory under the project root directory, and the git warehouse must
2. remote only needs to be executed once, yourRepository.git is a warehouse you already have in github
3. .gitignore, this file is written to all files that do not need to be added to version management, especially like node_modules

2. Create sub-projects
