git filter-branch删除文件夹失败 [英] git filter-branch remove folder failed
问题描述
我想从git repo上的提交中删除一个文件夹，所以我使用以下命令:
I want to remove a folder from commits on my git repo, so I use this commend:
git filter-branch --tree-filter 'rm -rf folder' HEAD
git push origin master --force
但是我的git repo上没有任何更改，那些包含我要在git repo上删除的文件夹的提交.
But there is no any change on my git repo, those commits which contain the folder I want to delete still on git repo.
所以我再试一次，但是显示:
So I try it again, but there shows:
.git-rewrite已经存在，请将其删除
.git-rewrite already exists please remove it
我不知道还能从永久包含git repo上的文件夹的所有提交中删除它.
I don't know what else can I do to remove it from all commits which contain the folder on git repo permanently.
推荐答案
为了从git存储库中完全删除文件或目录，您必须确保不再引用该文件或目录.
In order to remove a file or directory completely from a git repository you must ensure that it is not referenced anymore.
在git中，文件(或blob对象)由树对象引用，该树对象由另一个树对象或提交对象引用.提交对象由分支，标签和引用日志中的引用进行引用.
In git a file (or blob object) is referenced by a tree object which is referenced by either another tree object or a commit object. Commit objects are referenced by branches, tags, in the reflog and so on.
前一段时间，我不得不从项目中完全删除一个文件夹，并写了一个博客.所以我不想在这里重复自己.只需看看从git页面中永久删除目录和文件.
Some time ago I had to completely remove a folder from a project and wrote a blog about it. So I don't want to repeat myself here. Just take a look at Remove directories and files permanently from git page.
我还编写了一个使用 jgit 库的swing应用程序.只需尝试 GitDirStat .最好先复制当前的回购副本.
I also wrote a swing application that uses the jgit library to to this. Just try GitDirStat. Making a copy of your current repo before is always a good choice.
.git-rewrite已经存在，请将其删除
.git-rewrite already exists please remove it
只需按照消息中的说明进行操作即可.删除 .git-rewrite .
Just do what the message says. Remove .git-rewrite.
PS:您不必使用-tree-filter ，索引过滤器可以更快地完成操作；)然后，您必须使用 git rm -rf --cached .
PS: You don't have to use a --tree-filter an index filter will do it faster ;) Then you must use git rm -rf --cached.
