minification of angularjs project with grunt

I have a problem with injection when I minify my angularJS project with grunt. To do a simple test, I tried to do the same thing with the sample we have after creating a angular project with the npm generator like this : ``` npm install -g generator-angular yo angular ``` I add just a little things with bower. Here is my bower file : ``` { "name": "angular-test", "version": "0.0.0", "dependencies": { "angular": "1.2.15", "json3": "~3.2.6", "es5-shim": "~2.1.0", "jquery": "~1.11.0", "bootstrap": "~3.0.3", "angular-route": "~1.2.15", "angular-bootstrap": "~0.10.0", "angular-sanitize": "~1.2.15", "angular-cookies": "~1.2.15", "angular-resource": "~1.2.15" }, "devDependencies": { "angular-mocks": "1.2.15", "angular-scenario": "1.2.15" }, "resolutions": { "angular": "1.2.6" } } ``` Then I changed the app.js file like that : ``` 'use strict'; angular .module('angularTestApp', [ 'ngCookies', 'ngResource', 'ngSanitize', 'ngRoute' ]) .config(['$routeProvider', '$httpProvider', function ($routeProvider, $httpProvider) { $httpProvider.interceptors.push(function ($q) { //We don't care about that ... return { 'responseError': function (rejection) { if(rejection.status === 401) { console.log("Unauthorized page. Must redirect to "); return; } return $q.reject(rejection); } }; }); }]); ``` If I lauch the "grunt serve" task everything is ok. But, if I do a "grunt build" and then try to access the index.html file through Apache for example, I have the following error : ``` Uncaught Error: [$injector:unpr] Unknown provider: aProvider <- a <- $http <- $compile http://errors.angularjs.org/1.2.15/$injector/unpr?p0=aProvider%20%3C-%20a%20%3C-%20%24http%20%3C-%20%24compile ``` I read in few posts that I have to use the ngmin task to minify but it is already done in the sample yeoman project. Si How can I fix this please ? Thank you very much Clement
