创建了一个GitHub项目，将本地仓库的Java图书推上去，出现这个错误。
$ git push

Everything up-to-date
经过在StackOverFlow上查询得知，可能是上传的文件太大导致的：
git config http.postBuffer 524288000参见：https://stackoverflow.com/questions/6842687/the-remote-end-hung-up-unexpectedly-while-git-cloning
With this kind of error, I usually start by raising the postBuffer size by:
git config --global http.postBuffer 524288000
(some comments below report having to double the value):
git config --global http.postBuffer 1048576000因此设置 git config http.postBuffer 524288000 发现没有解决，尝试再增大一倍还是没有解决。
可能是网络问题，最后是通过每次提交部分文件,减少每次提交的文件总大小来解决的。
