Proper way to develop a WS client using JAX-WS and Maven's jaxws-maven-plugin

Hello,

I'm using "jaxws-maven-plugin" to generate WS stub classes, as shown below:

        <plugins>
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>jaxws-maven-plugin</artifactId>
                <version>1.12</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>wsimport</goal>
                        </goals>
                        <configuration>
                            <packageName>my.company.zte</packageName>
                            <wsdlUrls>
                                <wsdlUrl>http://192.168.14.31:9180/ZTE/ProvisionPortTypeService?wsdl</wsdlUrl>
                            </wsdlUrls>
                            <keep>true</keep>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>

This plugin binds to the "install" phase of the lifecycle. Sources and class files are generated properly, however IntelliJ didn't recognize them in the editor. So I added the WS classes directory in Module Settings / Dependencies. However, IDE still gives me "Incompatible types" errors on occassions, e.g. in this one:

    ProvisionPortType provisionPort = this.zteService.getProvisionPort()

gives "Incompatible types. Required my.company.zte.ProvisionPortType, found my.company.zte.ProvisionPortType"

Am I doing something wrong here? Is this the proper way to do this?
