Ionic package build command doesn't always build the latest code


I’m having some trouble while using the “ionic package build android” command (ionic 2). It does not always build the latest code. I noticed that I need sometime to stop the ionic serve processus and relaunch it, before to call the online build.

Is it the right process ? You need to serve before launching the online build or it is another issue ?

My system information:

ordova CLI: 6.4.0
Ionic Framework Version: 2.0.0-rc.2
Ionic CLI Version: 2.1.8
Ionic App Lib Version: 2.1.4
Ionic App Scripts Version: 0.0.43
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Windows 7
Node Version: v6.8.1

Thank you !
