Grunt build - empty main.js

[demiro]

After first setup

yo angular-jade-stylus --jade --stylus myApp

without even changing anything if I run grunt build

everything is done without errors, but checking .tmp/concat/scripts/main.js is EMPTY so uglify just gets this empty file and minifies nothing :)

thi is copied from the console

 concat:
  { generated:
   { files:
      [ { dest: '.tmp\\concat\\scripts\\vendor.js',
          src:
           [ 'app\\bower_components\\jquery\\dist\\jquery.js',
             'app\\bower_components\\es5-shim\\es5-shim.js',
             'app\\bower_components\\angular\\angular.js',
             'app\\bower_components\\json3\\lib\\json3.min.js',
             'app\\bower_components\\bootstrap\\dist\\js\\bootstrap.js',
             'app\\bower_components\\angular-resource\\angular-resource.js',
             'app\\bower_components\\angular-cookies\\angular-cookies.js',
             'app\\bower_components\\angular-sanitize\\angular-sanitize.js',
             'app\\bower_components\\angular-route\\angular-route.js',
             'app\\bower_components\\angular-bootstrap\\ui-bootstrap-tpls.js' ] },
        { dest: '.tmp\\concat\\scripts\\main.js',
          src:
           [ '.tmp\\scripts\\app.js',
             '.tmp\\scripts\\controllers\\main.js' ] } ] } }

it looks like that the .tmp\scripts folder is not there at all
