When we cloned cocos2d-x repo today and found the following error:

I see the failure. I tested and the following works:

git clone https://github.com/cocos2d/cocos2d-x
cd cocos2d-x/
git submodule update --init

Hey, I actually faced this issue. It is said here that the protocol git:// is outdated. You may do this as a workaround:

1. Replace urls in .gitmodules like this:

$git diff
...
 [submodule "tools/cocos2d-console"]
         path = tools/cocos2d-console
-        url = git://github.com/cocos2d/cocos2d-console.git
+        url = [email protected]:cocos2d/cocos2d-console.git
 [submodule "tools/bindings-generator"]
         path = tools/bindings-generator
-        url = git://github.com/cocos2d/bindings-generator.git
+        url = [email protected]:cocos2d/bindings-generator.git
 [submodule "tests/cpp-tests/Resources/ccs-res"]
         path = tests/cpp-tests/Resources/ccs-res
-        url = git://github.com/dumganhar/ccs-res.git
+        url = [email protected]:dumganhar/ccs-res.git

2. Sync the new urls: $git submodule sync --recursive
3. Now $git submodule update --init should work.

I don't know maybe they should update the submodule urls if it won't break something

Yes, the problem is back. I tried it and it works too, but it's better to fix it upstream, local patching is of no use to us.
