Compile widgetset with Spring Boot

Vaadin 6 / 7 / 8
1

Hello,

I’ve created a Vaadin project using Spring Boot (1.4.3) and use the vaadin-spring-boot-starter dependency (1.1.1). I also want to use the Highcharts for Vaadin 7 add-on (by Stefan Endrullis). I’ve tried without the AppWidgetset.gwt.xml and only spring-boot-maven-plugin in the build/plugins part of my POM but it’s not working… In the browser’s web inspector it says that my widgetset version is not up to date or something like this…

Do I really need to compile the widgetset if I want to use this add-on? Isn’t widgetset compilation automatically handled by vaadin-spring-boot-starter?

I’ve tried to copy stuff from https://github.com/joshlong/vaadin-and-spring-talk but when I do a clean install I get this error:

I’ve never really understood this widgetset thing so I’m a bit lost… If you need the source code I can take some time to put it on github…

Thanks a lot for your help!

Ok, so I’ve managed to get the add-on working… and the widgetset compilation wasn’t needed.
I would still be interested about the right way to compile widgetset using Spring Boot.
