git 拉新项目_Git子模块。拉入超级项目的新克隆

OK. So I thought I had this licked ... but now ....

I have a project which includes one small library from GitHub as a submodule. In the original version of that super-project the submodule is working as expected.

However, I just cloned the superproject, did what I thought I should : "git submodule init", got the directory of the submodule to appear, but it's empty.

If I now try to do

git submodule update

I get

fatal: Needed a single revision

Unable to find current revision in submodule path 'external_libraries/BEACHhtml'

If I try

git submodule foreach git pull

I get

Entering 'external_libraries/BEACHhtml'

fatal: Where do you want to fetch from today?

Stopping at 'external_libraries/BEACHhtml'; script returned non-zero status.

In my .git/config, I have this :

[submodule "external_libraries/BEACHhtml"]

url = git@github.com:interstar/BEACHhtml.git

In my .gitmodules I have this :

[submodule "external_libraries/BEACHhtml"]

path = external_libraries/BEACHhtml

url = git@github.com:interstar/BEACHhtml.git

Anyone got an idea what's missing?

解决方案

In short, for your problem, try:

# rm -rf external_libraries/BEACHhtml

# git submodule update

It seems there is something wrong with the previous checkout folder, remove it, and update again solves the problem.
