title: Debugging CoffeeScript in VSCode goes to .js files
body: <p>I am trying to debug a CoffeeScript file in vs code. It works and I can step through the compiled.js files. However, I can't step through the actual CoffeeScript files. </p>
  
  <p>Here is my launch.json file:</p>
  
  <pre><code>{
      "type": "node",
      "request": "launch",
      "name": "Launch Meeting",
      "program": "${workspaceRoot}/lib/meeting/meeting-service.coffee",
      "cwd": "${workspaceRoot}",
      "env": {
          "NODE_ENV": "local"
      },
      "sourceMaps": true
  }
  </code></pre>
  
  <p>And in another window, I am running: </p>
  
  <pre><code>./node_modules/.bin/coffee -mc --watch lib/activity/note-activity-model.coffee \
                                         lib/activity/note-activity-publisher.coffee \
                                         lib/app-event-queue.coffee \
                                         lib/meeting/meeting-api.coffee \
                                         lib/meeting/meeting-service.coffee \
                                         lib/meeting/meeting-socket-service.coffee \
                                         lib/meeting/meeting-util.coffee
  </code></pre>
  
  <p>When I set a breakpoint in the coffee file, the debugger halts on the compiled js file. I need it on the coffee file.</p>
