Error executing 010_add_platform_class.js using VS Tools for Apache Cordova

Question

I have imported an existing Ionic app into VS 2015 Update 1. I'm using the latest Tools for Apache Cordova Update 7. When I build the app, I'm getting the errors below when it tries to execute the hooks\after_prepare\010_add_platform_class.js file. If I remove the file, VS will build and execute the app fine. Is this a bug in TACO or am I doing something wrong?

Executing "after_prepare"  hook for all plugins.

Answer 1

This can happen if you're building in a project where your files are locked as read-only (for example, when using TFS source control). Upon build, there is a script used by Ionic to modify the home page of your app to add a CSS class that identifies your target platform. If your home page file (e.g. index.html) is marked as read only, try clearing that setting and build again.
