Hey Vaadin-Guys!
I need some help for my Widgetset-Maven-Module-Problem.
My Intention:
I have a Maven Module Project like this:
Widgetset-Project-Parent
|-
pom.xml
|-
Widgetset-Project-Basic
|-
pom.xml
|-
Widgetset-Project-Extended-Desktop
|-
pom.xml
|-
Widgetset-Project-Extended-Mobile
|-
pom.xml
My plan is that i have the Basic-Widgetset for my Extensions, that i need on Desktop and on Mobiles.
In the Extended-Desktop and Extended-Mobile i can create special Implementations for the Target-Environments. (They inherit the basic widgetset)
The intended Widgetset-Project-Extended-Desktop.gwt.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.5.0//EN" "http://google-web-toolkit.googlecode.com/svn/tags/2.5.0/distro-source/core/src/gwt-module.dtd">
<module>
<!-- Widgetset-Project-Basic: Inherits com.vaadin.DefaultWidgetSet -->
<inherits name="de.company.project.widgetset.basic.Widgetset-Project-Basic" />
<inherits name="some.other.Widgetsets" />
</module
[/code]This File should be generated from vaadin-maven-plugin at "update-widgetset"-Goal.
Here is the pom.xml of the Widgetset-Project-Extended-Desktop[code]

i get an Exception in my Maven Build at the goal vaadin.maven-plugin:resources
If i trust to the automatic resolution i get only my Widgetset-Desktop but not my Widgetset-Basic!

After correcting the problems, you can resume the build with the command
[ERROR]
mvn <goals> -rf :emesus-app-ui-vaadin-widgetset-desktopI have googled alot… But it looks, that nobody has a Project-Configuration like me…
Thank you for your help!
Greetings,
