Hi Herman,
Looking at your pom.xml configuration you are attempting to use the 1.1.0.GA version of maven-jaxws-tools-plugin. It does not exist in the jboss plugins repository.
http://repository.jboss.org/maven2/org/jboss/ws/plugins/maven-jaxws-tools-plugin/
1)
You need to change the version to
<version>1.0.0.GA</version>
2)
Check you have this plugin repository in your Maven settings.xml file.
<pluginRepository>
<id>jboss-plugins</id>
<url>http://repository.jboss.com/maven2</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</pluginRepository>
Regards,
Jeremy
