add submodule to git project and download it content -

i've create .gitmodules file content

[submodule "xxxx/src/main/webapp/js/app/ui"]     path = xxx/src/main/webapp/js/app/ui     url = git@github.com:xxx/task-core.git 

but how make content appear in src/main/webapp/js/app/ui? did

git submodule init git submodule update 

but folder still empty.

instead of manually adding submodule reference .gitmodules, use git submodule add. clean .gitmodules file, , try following:

git submodule add git@github.com:xxx/task-core.git -- xxx/src/main/webapp/js/app/ui 

then should see edited .gitmodules submodule directory listed in git status.

now time run:

git submodule init git submodule update
