CXF插件的Maven XML标签区分大小写，应该可以使用:

The Maven XML tags for the CXF plugin are case sensitive, this should work:

<configuration>
    <sourceRoot>${basedir}/src/main/java</sourceRoot>
    <wsdlOptions>
        <wsdlOption>
            <wsdl>${basedir}/src/main/resources/HostavailableService.wsdl</wsdl>
            <extraargs>
                <extraarg>-verbose</extraarg>
                <extraarg>-client</extraarg>
            </extraargs>
        </wsdlOption>
    </wsdlOptions>
</configuration>
