以windows为例
从fork项目开始
登录自己的github账号，fork一个项目，这里以 sharding-sphere 为例（顺便打一下广告^_^毕竟参与了项目）
1、登录github，打开项目主页sharding-sphere
2、点击页面的fork
3、fork完成可以在自己的github仓库中看到fork的项目sharding-sphere
clone项目到本地
1、git客户端选择
根据个人喜好，选择git shell或者纯桌面版git desktop。安装过程略，附下载地址 地址1、地址2、地址3
如果装的是纯桌面版，可以通过菜单打开git下载安装向导(省的搜索……)
2、在本地创建仓库存放的位置
本案例在d:\GitHub
3、克隆fork的项目到本地仓库
打开git shell
C:\Users\yueling>cd D:\GitHubD:\GitHub>git clone /yue530tom/sharding-sphere.git
Cloning into 'sharding-sphere'...remote: Counting objects: 87775, done.remote: Total 87775 (delta 0), reused 0 (delta 0), pack-reused 87775Receiving objects: 100% (87775/87775), 16.87 MiB | 63.00 KiB/s, done.Resolving deltas: 100% (42095/42095), done. ˻

同步更新到fork
1、添加新的远程仓库地址
查看你fork的远程仓库的地址
D:\GitHub> cd .\sharding-sphereD:\GitHub\sharding-sphere [dev ≡]> git remote -vorigin /yue530tom/sharding-sphere.git (fetch)origin /yue530tom/sharding-sphere.git (push)sharding-sphere /sharding-sphere/sharding-sphere.git (fetch)sharding-sphere /sharding-sphere/sharding-sphere.git (push)D:\GitHub\sharding-sphere [dev ≡]>
这里已经有项目的源地址了：sharding-sphere，如果没有，可以通过
git remote add 远端仓库别名 /sharding-sphere/sharding-sphere.git
来添加一个(仓库的别名，可以使用任何合法的名称，但建议用有标识意义的名称)
如：可以再添加一个别名为src的远程仓库
D:\GitHub\sharding-sphere [dev ≡]> git remote add src /sharding-sphere/sharding-sphere.gitD:\GitHub\sharding-sphere [dev ≡]> git remote -vorigin /yue530tom/sharding-sphere.git (fetch)origin /yue530tom/sharding-sphere.git (push)sharding-sphere /sharding-sphere/sharding-sphere.git (fetch)sharding-sphere /sharding-sphere/sharding-sphere.git (push)src/sharding-sphere/sharding-sphere.git (fetch)src/sharding-sphere/sharding-sphere.git (push)D:\GitHub\sharding-sphere [dev ≡]>
2、同步更新
当原项目有更新的时候，将更新检入到本地。
打开git命令行工具并进入项目本地路径
D:\GitHub\sharding-sphere [dev ≡]>
执行git fetch src命令，检出src分支以及各自的更新
D:\GitHub\sharding-sphere [dev ≡]> git fetch srcremote: Counting objects: 4962, done.remote: Compressing objects: 100% (611/611), done.remote: Total 4962 (delta 2488), reused 3099 (delta 2431), pack-reused 1776Receiving objects: 100% (4962/4962), 1.04 MiB | 209.00 KiB/s, done.Resolving deltas: 100% (2845/2845), completed with 388 local objects.From /sharding-sphere/sharding-sphere* [new branch]dev -> src/dev* [new branch]master -> src/master* [new branch]sharding-console -> src/sharding-consoleD:\GitHub\sharding-sphere [dev ≡]>
切换到你的本地分支
D:\GitHub\sharding-sphere [dev ≡]> git checkout devAlready on 'dev'Your branch is up-to-date with 'origin/dev'.D:\GitHub\sharding-sphere [dev ≡]>
合并src/dev分支和dev分支
D:\GitHub\sharding-sphere [dev ≡]>git merge src/dev……rename {sharding-jdbc-core => sharding-jdbc}/src/test/resources/integrate/dataset/sharding/tbl/expect/update/tbl_9.xml (100%)rename {sharding-jdbc-core => sharding-jdbc}/src/test/resources/integrate/dataset/sharding/tbl/init/tbl.xml (100%)create mode 100644 sharding-jdbc/src/test/resources/integrate/dbtest/db/data-init.xmlcreate mode 100644 sharding-jdbc/src/test/resources/integrate/dbtest/db/schema.xmlcreate mode 100644 sharding-jdbc/src/test/resources/integrate/dbtest/db/sharding-rule.yamlcreate mode 100644 sharding-jdbc/src/test/resources/integrate/dbtest/dbtbl/data-init.xmlcreate mode 100644 sharding-jdbc/src/test/resources/integrate/dbtest/dbtbl/schema.xml …… D:\GitHub\sharding-sphere [dev ↑235]>
将原项目中的更改更新到本地分支，这样就能使你的本地的fork分支与原项目保持同步
可以用git pull命令代替上面操作。作用：取回远程主机某个分支的更新，再与本地的指定分支合并
git pull [options] [ […]]
执行git push将本地分支的修改推送到远端fork的项目
D:\GitHub\sharding-sphere [dev ↑235]> git pushCounting objects: 4963, done.Delta compression using up to 4 pressing objects: 100% (1915/1915), done.Writing objects: 100% (4963/4963), 1.17 MiB | 113.00 KiB/s, done.Total 4963 (delta 2592), reused 4568 (delta 2455)remote: Resolving deltas: 100% (2592/2592), completed with 62 local objects.To /yue530tom/sharding-sphere.git5ff9b0417..37cde1fee dev -> devD:\GitHub\sharding-sphere [dev ≡]> git checkout devAlready on 'dev'Your branch is up-to-date with 'origin/dev'.D:\GitHub\sharding-sphere [dev ≡]>
登录github确认是否已经更新了
git（非纯桌面版）的sync也可以实现项目的同步
选择需要比较的分支，选择配置的源仓库对应的分支，这点很重要比如选择src（上面已经用到过）
传送门：github web页面上直接同步源项目更新
