[EduFrazao]

Hi Tomi! Thanks for you nice addon. I cant compile your addon here. Im using Vaadin 7.0.4 (Maven based project).

I've alread excluded GWT Unit Cache files, but I got this problem in widgetset compilation:

Steps to reproduce:
Create a new Vaadin Project with Maven:
mvn archetype:generate -DarchetypeGroupId=com.vaadin -DarchetypeArtifactId=vaadin-archetype-application -DarchetypeVersion=7.0.4 -DgroupId=your.company -DartifactId=project-name -Dversion=1.0 -Dpackaging=war

Addon the plugin depedency on pom:

org.vaadin.virkki
carousel
0.5.2

Is somethind that I'm doint wrong? I only added the plugin dependency on my POM.XML

Thanks!

Hi Tomi. Making some testes here, I've noted that if you disable the GWT Compilation Strict Mode, compilation works, and component performs well too. I think that with the default classpath generated by Maven Build, theres some library conflict (Google Guava, the collection part (Iterators helper)). The selected class does not have the method signature used by xtext base. I cant figure out what jar is causing the conflict.

Hi Eduardo
Updated the Carousel to use xtend/xtext 2.4.1 and tried with a newer guava-gwt version but the problem still remains :( The stack trace suggests it's an xtext gwt library issue but cannot tell for sure. For now strict mode must be disabled for compilation.
