Grunt usemin task no funciona en archivos anidados al tiempo que reduce archivos angulares

Question

La estructura de mi documento es root-> public-> angular-> scripts-> main-> app.js. He usado el generador angular yeoman y configuré el gruñido. Mi archivo html se ve así

 <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>

El archivo html está en la raíz-> público-> angular. Después de ejecutar grunt, la carpeta .tmp y dist contiene archivos minificados de bower_components. Pero scripts.js está vacío. Si coloco app.js fuera de la carpeta principal en scripts, se concatenará en tmp / scripts.js. ¿Por qué esto es así? Qué estoy haciendo mal ??

Lea la nota sobre globbing en la parte superior: debe cambiar todas las {,*/}* por **/* ya que sus scripts no tienen un solo nivel de profundidad (es decir, scripts / app.js vs. scripts / carpeta / aplicación .js)
