ti build failes when Ti project has special kind of image assets (Logo.png, SplashScreen.png) with invalid dimension. This happens especially when you bring Ti project from other platforms which already has splash screen / app icon assets, like [Movies](
https://github.com/appcelerator/movies) app.

Possible workaround would be to convert these images to valid dimension at pre-build, or just ignore these special assets only when it has invalid dimension.
To check the size of these images, we use the png-size NPM module. It works pretty great. To resize images, I wrote a cross-platform Java CLI tool that uses imgscalr for mobile web. I use it to resize the DefaultIcon.png to generate missing app icons. Here's the ticket for initial support for DefaultIcon.png: TIMOB-19477. I created you a Windows-specific ticket: TIMOB-19487. So, after I finish TIMOB-19477, then you will simply be able to call the generateAppIcons() method from the base Builder object and have it resize the DefaultIcon.png into as many other images as you'd like. Because the resizing uses Java, you will want to get a list of all images to resize, then pass them all in once.
Fixed by TIMOB-19487
Closing ticket as fixed.
