AppWidgetset with fetch mode does not work
Eclipse downloads the files but some part of incremental build removes all content from the download folder immediately after the download finishes.
Workaround: Use local compilation or CDN
We do recommend using the local compilation for production and CDN/fetch for development anyway. So at least when developing you can make things faster.
@tsuoanttila, do you have an example/guidelines how to properly configure a Vaadin multimodule project for development and production use so that development profile uses CDN to speed things up and production profile uses local compilation to avoid CDN dependency in production? Can some good Vaadin developer advocate create a blog post about this perhaps?
