Error compilation with on vaadin 8

[radekpakula]

Hi there is problem in WidgetsetDefinition in file fi/jasoft/dragdroplayouts/public/DragDropLayoutsWidgetSet.gwt.xml

When try compile widgetset on my project (vaadin 8, addon version 1.4.2) i recive error that "com.vaadin.v7.Vaadin7WidgetSet" is not found. I remove problematic line and recompile widgetset in my project. Looks good and work fine.

//Edit
It looks that in branch tagged 1.4 file looks fine. Problem occurs with package addon version 1.4.2 in vaadin repository. File fi/jasoft/dragdroplayouts/public/DragDropLayoutsWidgetSet.gwt.xml is out of date.

@radekpakula thank you for noticing this issue. It's caused by the fact that we depend on the compatibility widgetset from Framework 8. If you don't have the compatibility packages (see for example https://vaadin.com/vaadin-fw8-documentation-portlet/framework/migration/migrating-to-vaadin8.html), then the compilation will fail. In the future we could consider somehow splitting the compatibility classes to a separate download.

@ripla at https://vaadin.com/directory#!addon/dragdroplayouts it says that this addon supports vaadin 8. Please either provide information on how to get it to work with vaadin 8 (for example which "compatibility" maven packages are missing exactly?) or change the compatibility information in the vaadin directory.

@basisbit you most likely need these maven artefacts:

• vaadin-compatibility-server
• vaadin-compatibility-client
• vaadin-compatibility-shared

see #88 to get a jar file that build cleanly with vaadin8 without the need for compability packages

I'm still see the same issue for addon from vaadin repository for the latest version.
