I use the grunt usemin plugin to pile my requirejs files. In my html page I have the following snippet:

<!-- build:js ../dist/app.min.js -->
<script data-main="js/modules/app" src="../lib/js/requirejs/requirejs.js"></script>
<!-- endbuild -->

and this is my grunt file:

/*global module:false*/
module.exports = function(grunt) {

  // Project configuration.
  grunt.initConfig({
    pkg: '<json:package.json>',
    //run jshint, the busterjs tests and pile the handlbar templates every time a file changed
    watch: {
      files: ['Gruntfile.js', 'dev/js/*.js', 'test/**/*.js', 'dev/templates/*.hbs'],
      tasks: ['jshint', 'buster', 'handlebars']
    },
    //hint all the js files
    jshint: {

    //create md5 file names for all minified sources
    md5: {
      pile: {
        files: {

        },
        //overide the pathes in the index.html with the new md5 name
        options: {
          callback: function(newPath, oldPath, content) {
            var fs = require('fs')
            fs.unlink(oldPath);

            var replacedData = file.replace(oldPath.replace('dist/', ''), newPath.replace('dist/', ''));

          }

    },
    //create a manifest file for all js and css files
    manifest: {
      generate: {

        ],

When I run the dist task everything works well but the requirejs task quits with:

Running "requirejs:out" (requirejs) task

But straight before the usmin task logs this:

• javascript
• requirejs
• gruntjs

Seems a bug in usemin, as the current version dont support a multitask version of the requirejs task.
