javascript - How to configure grunt-contrib-uglify to minify files while retaining directory structure -

in case have multiple subdirectories under 'js' directory in example gruntfile posted below, , want retain subdirectories under different destination directory, how do it?

for e.g.

module.exports = function (grunt) {     grunt.initconfig({         // define source files , destinations        uglify: {            files: {                 src: 'js/**/*.js',  // source files mask                dest: 'minjs/',    // destination folder                expand: true,    // allow dynamic building                flatten: true,   // remove unnecessary nesting            }        }     });      // load plugins     grunt.loadnpmtasks('grunt-contrib-uglify');      // register @ least 1 task     grunt.registertask('default', [ 'uglify' ]); }; 

in case, have shown */.js, if explicitly specify single subdirectory js/xyz/*.js not copying directory structure, instead seems put files within subdirectory under minjs/ folder in example. missing here? please help.

thanks,
