cloning submodule fails

I am trying to clone a submodule for my drupal installation. I run the following command:

git submodule add http://git.drupal.org/project/token.git /sites/all/modules/token

This throws this error:

The following path is ignored by one of your .gitignore files:
/sites/all/modules/token
Use -f if you really want to add it.

But my .gitignore file is empty.

So开发者_StackOverflow I tried to run it as suggested:

submodule add -f http://git.drupal.org/project/token.git /sites/all/modules/token

But this throws this error:

fatal: could not create leading directories of '/sites/all/modules/token': Permission denied
Clone of 'http://git.drupal.org/project/token.git' into submodule path '/sites/all/modules/token' failed

Permissions are 777.

Ideas?

Just found the answer:

git submodule add http://git.drupal.org/project/token.git sites/all/modules/token

The leading "/" was the problem.

I had the same problem, but apparently for different reasons. I tried to use git submodule add like I used git clone - without specifying the directory like this:

git submodule add ../repos/subA instead of git submodule add ../repos/subA subA

All I have to say is that is the effing worst error message possible to tell me I left off a required command-line argument.
