The gwt-maven-plugin Archetype creates a bare bones GWT application with all the gwt-maven-plugin setup and structure in place (a template).
Use it as you would any other Maven archetype to create a template/stub project.
mvn archetype:generate \ -DarchetypeGroupId=org.codehaus.mojo \ -DarchetypeArtifactId=gwt-maven-plugin \ -DarchetypeVersion=1.1 \ -DgroupId=myGroupId \ -DartifactId=myArtifactId
Note: don't run mvn archetype:create as the plugin uses archetype NG descriptor.
