How can I modify the main ember cli app tree of an ember app

I am wondering if there is a way to modify the app tree. For example, lets say I have a component located in app\components\my-component.js . I want to totally ignore this component and not build it into the project. Is this possible?

I tried adding the following lines in my ember-cli-build :

var appTree = new Funnel(app.toTree(), {
    exclude: ['my-component.js']
});

But I believe that app.toTree() returns the tree after it has been minified and merged into a single assets/my-app.js . So it seems it is too late here. Is there anyway I can do this? Thank you.

Use case is, for example, if I have a single ember project, but I want to build it for different targets (whatever targets could be, let's say french and english) , I want to be able to completely exclude some files belonging to the other target, while building for another.
