【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 
背景：osc 合作账号登录，3个月前创建的项目，过程不描述了。前一阵开始用git，安装和使用参考git@osc的帮助文档（传送门：http://www.liaoxuefeng.com/wiki/0013739516305929606dd18361248578c67b8067c8c017b000）。为了方便开发，后续直接clone项目到本地，问题是clone，add，远程仓库等都没问题，只是Push时一直抛出权限问题 " Please make sure you have the correct access rights and the repository exists" 。用一段Github后继续搞起，发现自己当时犯的几个白痴错误一一列举，遇到同样坎的朋友可以参考。
1. 克隆项目到本地， add 和添加到远程仓库，一切都是顺利的

错误一：将publich key错误添加到项目的部署公钥中，一定注意是加到自己账号的公钥中，地址：http://git.oschina.net/keys。
错误二：SSH配置有问题，参考了Jackin的文档，后面的添加key到/etc/.ssh/ssh_config一步，因为我本身机器中的文件没有配置，所以没有按照文档做。

这样就成功了，开会去了，先写这么多。
