the git clone is empty? why this happens

Question

This always perplexes me. I was cloning this

git clone https://android.googlesource.com/kernel/msm.git

And It seemed to be cloning resolving

Answer 1

After your first clone, if you have directories that are submodules of the parent repo, you need to initialize them with:

git submodule update --init

Using git submodule update --init --recursive will also be needed if there are submodules inside submodules.
