gruntjs - yeoman/grunt task : copy a folder to dist -

i new yeoman , grunt, , don't how copy folder created in app directory dist directory.

the folder /data/locales/lng/_ns_.json , there several lng folders , multiple ns files.

i copy whole structure dist directory.

i tried copy task , added :

{     cwd: '<%= yeoman.app %>',     dest: '<%= yeoman.dist %>',     src: [         'data/**/*.{json}'     ] }

but doesn't work...

"i copy whole structure dist directory."

this should it:

{     cwd: 'data',     dest: 'path/to/dest',     src: ['**'] }

this copy files , directories within 'data' directory destination directory.
