Hi all, this is what I get when trying to recompile my widgetset with Vaadin 7.2.0:

[/code]Is there anything I have to change in my project, or is it a bug?

Thanks,

The errors indicate to me that you might be using some older version of GWT which is incompatible with Vaadin 7.2.

To ensure that you start from a clean slate remove any previously compiled widgetset and also remove any unit-Cache directory the compiler might have previously created.

Also, check your classpath that you don’t have any gwt jar dependencies.

Hi

I have a similar issue. Widgetset compilation worked the very first time after the upgrade from 7.1.15 to 7.2.0.

If I try again it fails with the following exception pasted below. I can get arround by either manually deleting the folder gwt-unitCache oder by setting false in the vaadin-maven-plugin configuration

Thanks John, I actually forgot to replace the old lib/vaadin/vaadin-client-7.1.x.jar and vaadin-client-compiler-7.1.x.jar with the newest versions.
Now everything recompiles (but I still get lots of WARNings about “referencing deprecated class com.vaadin.shared.ui.progressindicator.ProgressIndicatorState”).

Thanks,
Marco

I was wondering about all those warnings as well when upgrading from 7.1.15.
