Hallo,
i use maven to compile and build my vaadin application. I can use the vaadin eclipse Plugin to compile the widgetset and it’s works fine. When i use maven to build my application it doesn’t work. I get this error:

I don’t know why this happend, because it works fine the hole time. Because of this error i update my Vaadin Version from 6.5.0 to 6.6.0.
Other Versions:

  • gwt-maven-plugin 2.2
  • gwt-user 2.3
  • gwt-dev 2.3
  • vaadin-maven-plugin 1.0.1
  • javax.validation-api 1.0.0.GA
  • javax.validation-api-sources 1.0.0.GA

Furthermore i use the addon ICEPush in Version 0.2.1 in my application.

Greetz,
Michel

Sound like some kind of classpath conflict, as described in
the GWT issue tracker
.

For all who have the same problem, edit your pom.xml and add this line
true
 to the configuration tag of the plugin tag.

org.codehaus.mojo
gwt-maven-plugin
2.2.0



${project.build.directory}/${project.build.finalName}/VAADIN/widgetsets
-Xmx512M -Xss1024k
clean
${project.build.directory}/${project.build.finalName}
true
8080
false
true

…

You lifesaver :wink:

For those using Intellij, an “Invalidate caches/restart” from the File menu seems to screw with the classpath order (although this has only happenned once), this fix works great.

Michael Klein, I dunno if you are still here. But seriously thank you!
