使用目录作为外部的 Git 存储库

Question

I have an SVN repository with some documents using the same reference (bibtex) files via svn:externals. Its contents looks like this:

bibtex/
doc1/
-doc1.tex
-bibtex/ (svn:externals)
doc2/
-doc2.tex
-bibtex/ (svn:externals)

This way I could checkout each paper individually and obtaining the same reference. How can I setup the same with git?

I read that submodules were suggested, but if I try (after git svn clone)

git submodule add ./bibtex ./doc1/bibtex

I obtain

fatal: repository '/home/user/repo/bibtex' does not exist
Clone of '/home/user/repo/bibtex' into submodule path 'doc1/bibtex' failed

Answer 1

You need to make sure bibtex is in its own Git repository. Which is not how svn external is used, since it is a "relative external" link to a folder of the same repository.

Plus, after a git svn clone , you could reorganize your Git repo only if you do not intent to git svn dcommit back to the SVN repository.

If that is the case, then yes, you could:

• split bibtext in its own repository
• push it to a new remote empty repo
• add it as submodule in your original repo

That is:

cd /path/to/svl-cloned/repo
cd doc1
git rm -r bibtex/
git commit -m "remove bibtex"
git submodule add /url/remote/bibtex/repo bibtex
git add .
git commit -m "Add bibtex submodule"
