准备工作：
1.准备好本地目录，这次我选择的是21年秋季的作品PicturesShow，内含5个文件和一个子目录，程序在子目录中。
2.在码云上新建一个项目PicturesShow，并记下其网址 https://gitee.com/heyang78/pictures-show.git
3.如果没有git，到 https://gitforwindows.org/ 下载Git for windows,然后安装好，一路next即可。
之后进入目录C:hygiteepicturesShow，右键点空白处选Git bash，打开Git控制台。
往下就是命令执行过程：
ufo@DESKTOP-82T142Q MINGW64 /c/hy/gitee/picturesShow $ git init Initialized empty Git repository in C:/hy/gitee/picturesShow/.git/ ufo@DESKTOP-82T142Q MINGW64 /c/hy/gitee/picturesShow (master) $ git add *.* ufo@DESKTOP-82T142Q MINGW64 /c/hy/gitee/picturesShow (master) $ git add . ufo@DESKTOP-82T142Q MINGW64 /c/hy/gitee/picturesShow (master) $ git commit -m "First Commit" [master (root-commit) 31296c6] First Commit 8 files changed, 603 insertions(+) create mode 100644 2021-08-08_080952.png create mode 100644 PicturesShowSrc/setting.txt create mode 100644 PicturesShowSrc/src/com/hy/Inlet.java create mode 100644 PicturesShowSrc/src/com/hy/ShowGui.java create mode 100644 README.md create mode 100644 picturesShow.jar create mode 100644 run.bat create mode 100644 setting.txt ufo@DESKTOP-82T142Q MINGW64 /c/hy/gitee/picturesShow (master) $ git remote add origin https://gitee.com/heyang78/pictures-show.git ufo@DESKTOP-82T142Q MINGW64 /c/hy/gitee/picturesShow (master) $ git push -u origin master Enumerating objects: 14, done.

上面的步骤中，"git add . " 是把子目录带入的关键一句话。
执行 git push -u origin master之后，软件会跳出对话框让你输入用户名密码，按实输入即可，如果git提示你装.net，不要理会，push工作仍会进行。
执行完毕后，刷新码云上项目PicturesShow，看到文件已经推送到其中，说明上传成功了。
