# .git目录过大问题 #

最近拉取一个项目代码时，发现其`.git`目录过大，尤其`.git/objects/pack`目录特别大。

原因是之前没有写好`.gitignore`文件，导致把`target`目录中构建出来的jar包等都提交到远程代码库上，即使后面在`.gitignore`里面加上了过滤，`.git`目录中还是会记录已提交的这些大文件。

查看`.git`目录中最大的10个文件：

git rev-list --objects --all | grep -f <(git verify-pack -v .git/objects/pack/*.idx| sort -k 3 -n | cut -f 1 -d " " | tail -10)

去掉不小心提交上去的`target`目录下的`*.jar`：

git filter-branch --index-filter 'git rm --cached --ignore-unmatch *.jar' -- --all
    rm -Rf .git/refs/original
    rm -Rf .git/logs/
    git gc --aggressive --prune=now

重复执行上面命令来过滤其它文件，比如 `.class` ，`.exec`和`.war`等。

查看本地`.git`目录大小，验证是否“瘦身”成功。

提交到远程代码仓库:

git push --force

> 在GitLab上需要先取消protect branch，否则GitLab不允许强制push到protected branch

> 如果不小心提交了敏感消息，最好是整个repository硬删除，再重新提交一个新的repository。
