pub build does not work for "example" folder

[MikeMitterer]

It results in a bunch of error messages - see below. The same app in web works without problems... This bug is really annoying because it makes it really hard to build multiple Angular samples for one package...

I know that I can provide full samples with pubspec.yaml and web-folder in example like you do it in your example folder but if this is the way to go then there should be at least a better error message.

For example I can pub build example for: https://github.com/MikeMitterer/dart-wsk-material but pub build example fails for: https://github.com/MikeMitterer/dart-wsk-angular
