No submodule mapping found in .gitmodules for path 'webroot/js/jstree'

Hi,

I added Idbroker dev_cake2.0 branch to my project.

$ git submodule add -b dev_cake2.0 https://github.com/analogrithems/idbroker.git app/Plugin/Idbroker

I found .gitmodules under app/Plugin/Idbroker, so I try to update submodules. Then I got this error.

$ cd app/Plugin/Idbroker
$ git submodule update --init
No submodule mapping found in .gitmodules for path 'webroot/js/jstree'

It seems that the master branch is also same.
