I've spent a couple of days on https://jira.jboss.org/jira/browse/JBWS-2650, ie. on providing a maven plugin for our jaxws tool frontends (wsconsume, wsprovide).
The org.jboss.ws.plugins:maven-jaxws-tools-plugin plugin lives in a subproject depending on jbossws-spi. The sources are available at http://anonsvn.jboss.org/repos/jbossws/projects/plugins/maven/jaxws-tools/trunk/
The plugin project currently uses the maven invoker plugin for testing itself with the native, cxf and metro stacks.
You can give it a try including it in your project pom.xml, currently version 1.0.0-SNAPSHOT is available on the repository:
If there're no complaints or special needs for the first version, I'm going to tag and release a first final version on Monday. Documentation coming to the wiki.
