Hello
I have run into a problem when I tried to add submodule into my project that is controlled by GIT. I got an error:
% git submodule add /submodule /project/submodule fatal: transport 'file' not allowed fatal: clone of '/submodule' into submodule path '/project/submodule' failed
The solution of this error is setting the global value always for file protocol in GIT like this:
git config --global protocol.file.allow always
That’s it!
