Compiling coffeescript files with grunt - coffeescript

Question

I am trying to write a grunt task to compile numerous .coffee files to corresponding .js files and .map files using grunt. I have the grunt coffee plugin, but there are some problems:
It compiles all files into one common destination folder instead of keeping the .js files in same folder as the .coffee file.
It merges two .coffee files of the same name in different directories into one file in the destination directory.
Please help solving these:
Grunt plugin: https://www.npmjs.org/package/grunt-contrib-coffee
Gruntfile.coffee:
module.exports = (grunt) ->
grunt.initConfig(
pkg: grunt.file.readJSON 'package.json'
coffee:
coffee_to_js:
options:
bare: true
sourceMap: true
expand: true
flatten: true
cwd: "client"
src: ["**/*.coffee"]
dest: 'client'
ext: ".js"
)
#Load Tasks
grunt.loadNpmTasks 'grunt-contrib-coffee'
grunt.registerTask('compile', ['coffee']);
null
Compiled Gruntfile.js
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
coffee: {
coffee_to_js: {
options: {
bare: true,
sourceMap: true
},
expand: true,
flatten: true,
cwd: "client",
src: ["**/*.coffee"],
dest: 'client',
ext: ".js"
}
}
});
grunt.loadNpmTasks('grunt-contrib-coffee');
grunt.registerTask('compile', ['coffee']);
return null;
};

If you want to maintain the structure of where your JS is compiled, you should set the flatten flag to false. See Grunt Configuring tasks - Building the files object dynamically.
module.exports = (grunt) ->
grunt.initConfig
pkg: grunt.file.readJSON 'package.json'
coffee:
coffee_to_js:
options:
bare: true
sourceMap: true
expand: true
flatten: false
cwd: "client"
src: ["**/*.coffee"]
dest: 'client'
ext: ".js"
#Load Tasks
grunt.loadNpmTasks 'grunt-contrib-coffee'
grunt.registerTask 'compile', ['coffee']
This is the output when not flattened which I believe is what you're after:
$ grunt compile
