Grunt usemin task che non funziona su file annidati mentre si minimizzano i file angolari

Question

La struttura del documento è root-> public-> angular-> script-> main-> app.js. Ho usato il generatore angolare yeoman e ho montato il grugnito. Il mio file html è simile a questo

<div> 
    <script src="bower_components/jquery/jquery.js"></script> 
    <script src="bower_components/angular.js"></script> 

    <!-- build:js scripts/plugins.js --> 
    <script src="bower_components/bootstrap/js/bootstrap-alert.js"></script> 

    <!-- endbuild --> 

    <!-- build:js scripts/modules.js --> 
    <script src="bower_components/angular-bootstrap/ui-bootstrap-tpls.js"></script> 

    <!-- endbuild --> 

    <!-- build:js scripts/scripts.js --> 
    <script src="scripts/main/app.js"></script> 

    <!-- endbuild --> 
</div> 

Il file html è in root-> public-> angular. Dopo aver eseguito grunt, il .tmp e la cartella dist contiene file miniati da bower_components. Ma scripts.js è vuoto. Se posto app.js al di fuori della cartella principale negli script, allora è concatenato in tmp/scripts.js. Perché è così? Che cosa sto facendo di sbagliato ??

My grunt.js file 

    // Generated on 2013-12-06 using generator-angular 0.6.0 
'use strict';

    // Define the configuration for all the tasks

leggere la nota sul globbing in alto - è necessario cambiare tutto il {,*/}* per **/* poiché i vostri script non sono un unico livello profondo (cioè scripts/app.js vs. scripts/cartella/app. js)
