Ember-cli how to change input path of files - ember.js

Question

I am new to ember. But for a particular task i need to change input path of templates to compile. i.e default is app/templates. but i want to change this path.
I have read the ember-cli-build.js file but i can edit only output path. how can i edit the input path.
My ember-cli-build.js
var EmberApp = require('ember-cli/lib/broccoli/ember-app');
module.exports = function(defaults) {
var app = new EmberApp(defaults, {
// Add options here
outputPaths: {
app: {
html: 'ember_build_index.html'
}
}
});
// Use `app.import` to add additional libraries to the generated
// output files.
//
// If you need to use different assets in different
// environments, specify an object as the first parameter. That
// object's keys should be the environment name and the values
// should be the asset to use in that environment.
//
// If the library that you are including contains AMD or ES6
// modules that you would like to import into your application
// please specify an object with the list of modules as keys
// along with the exports of each module as its value.
app.import('bower_components/bootstrap/dist/js/bootstrap.min.js');
app.import('bower_components/bootstrap/dist/css/bootstrap.min.css');
app.import('bower_components/bootstrap/dist/css/bootstrap.css.map');
return app.toTree();
};

You have to change templates directory path for the ember app being built.
To check your current templates directory path, check app.trees.templates._directoryPath in your ember-cli-build.js by log it to console using console.log(app.trees.templates._directoryPath) .
Now, if you want your ember build to have templates from 'app/templates/mobile' (in your case), just change:
app.trees.templates._directoryPath = 'app/templates/mobile' in ember-cli-build.js before it returns app.toTree();
The node_module which constructs tree for templates is at 'node_modules/ember-cli/lib/broccoli/ember-app.js' at line no. 724 where it accesses 'this.trees.templates' in which this is the instance of your app.
