error: hook declined to update refs/heads/external_pub while pushing a branch
提问by TDHM
Currently, I'm working on 'external_pub' branch. I made few changes in one file, added it, committed & then tried to push:
目前，我正在“external_pub”分支上工作。我在一个文件中做了一些更改，添加了它，提交了然后尝试推送：
git push origin external_pub
But this was resulted into an error:
但这导致了错误：
remote: error: hook declined to update refs/heads/external_pub
To ssh://XXX/testing.git
! [remote rejected] external_pub -> external_pub (hook declined)
error: failed to push some refs to 'ssh://XXX/testing.git'
Then I tried to push branch without any change to see what happens(just for isolating issue). I did following:
然后我尝试在没有任何更改的情况下推送分支以查看会发生什么（仅用于隔离问题）。我做了以下：
git reset --hard <commit_id> (to reset to last working sha commit)
git status
Above command showed:
上面的命令显示：
# On branch external_pub
# Your branch is ahead of 'development' by 5 commits.
#
nothing to commit (working directory clean)
Then
然后
git pull origin external_pub
It showed: your branch is already upto date
它显示：您的分支已经是最新的
Then
然后
git push origin external_pub
This time also, it showed the same error as above. Could you please help me to solve this?
这一次，它也显示了与上面相同的错误。你能帮我解决这个问题吗？

There's a git hookon the server that rejected the push. Quoting:
服务器上有一个拒绝推送的git 钩子。引用：
These scripts run before and after pushes to the server. The pre hooks can exit non-zero at any time to reject the push as well as print an error message back to the client; you can set up a push policy that's as complex as you wish.
这些脚本在推送到服务器之前和之后运行。pre hooks 可以随时退出非零以拒绝推送并将错误消息打印回客户端；您可以设置任意复杂的推送策略。
To find out why, you need to know what the hook does. Hooks are stored in hooksfolder inside the git folder (on the remote end) - find the pre-receivehook or updatehook and examine that.
要找出原因，您需要知道钩子的作用。钩子存储在hooksgit 文件夹内的文件夹中（在远程端） - 找到预接收钩子或更新钩子并检查它。

In OSX its usually caused by missing GEM's between brew ruby install and Apple ruby 2.0 (default).
在 OSX 中，它通常是由于 brew ruby install 和 Apple ruby 2.0（默认）之间缺少 GEM 造成的。
An include 'require json/ext/parser' or similar add-on is not found and exceptions at the require point.
未找到 include 'require json/ext/parser' 或类似的附加组件，并且在 require 点出现异常。

I resolved this issue. Normally I use VSTSID (Visual Studio Team Services) in message while committing code. Use the steps below:
我解决了这个问题。通常我在提交代码时在消息中使用 VSTSID（Visual Studio Team Services）。使用以下步骤：
git commit --amend (now its time to edit your commit message)
git commit -m "vs[your_vsts_id]-your_commit_message>" then press
i(keyboard button)
Esc(keyboard button)
:wq(to save)
git commit --amend（现在是编辑提交信息的时候了）
git commit -m "vs[your_vsts_id]-your_commit_message>" 然后按
i（键盘按钮）
Esc（键盘按钮）
:wq(保存)
After that you will be able to push(git push).
之后，您将能够推送（git push）。
If you still facing the issue, type git reset --soft HEAD^in git bash. Now you can see all your files in green color. It means, files are again ready for commit. Depending on your requirement, you can use reset (git reset) command as well.
如果您仍然遇到问题，请输入git reset --soft HEAD^git bash。现在您可以看到所有文件都显示为绿色。这意味着，文件再次准备好提交。根据您的要求，您也可以使用 reset ( git reset) 命令。

In case you are using Redmine Git Hosting, check your projet permissions Managerrole has been assigned to the user that is trying to rewrite his/her git's tracking references.
如果您使用的是Redmine Git Hosting，请检查您的项目权限管理器角色是否已分配给尝试重写其 git 跟踪引用的用户。
Please note that I am assuming you are aware on git push -forceimpact on the other users that may be sharing the same remote branch. For further details, check this article
请注意，我假设您知道git push -force对可能共享同一远程分支的其他用户的影响。有关更多详细信息，请查看这篇文章
