Open dangerground opened 6 years ago

dangerground commented 6 years ago

GWT version: 2.8.2 Browser (with version): all Operating System: debian testing

Description

the gwt compiler shows some problems when using -war parameter and adding an for the GridFastNavigation vaadin plugin element to the Widgetset. It does work on a clean project.

Steps to reproduce

Unfortunatly I can't provide an always working minimal example, but using https://gist.github.com/dangerground/8b5db377eca3896917037e37f0dd8f1d

You need to initialize a new gradle project then comment-out the GridFastNavigation inherit build the project and then comment-in again and build again. It will fail with the following log

I have the same problem - thank you for the workarounds - with cleaning beetween builds it worked for me. For sure it's only a workaround ...
