Running a grunt task on one Gruntfile from another

Question

I have a Gruntfile in the root of my project. I also have jQuery installed via Bower in an app/components/jquery directory.

As part of my Gruntfile I\'d like to run

Answer 1

You can create a simple task that spawns grunt in the folder you want:

grunt.registerTask('run-grunt', function () {
    var done = this.async();
    grunt.util.spawn({
        grunt: true,
        args: [''],
        opts: {
            cwd: 'app/components/jquery'
        }
    }, function (err, result, code) {
        done();
    });
});
