如何让Maven为我的项目生成jnlp？

   <groupId>org.codehaus.mojo</groupId>
   <artifactId>webstart-maven-plugin</artifactId>
   <version>1.0.1</version>
    <executions>
       <execution>
            <goals>
                <goal>jnlp</goal>
            </goals>
        </execution>
    </executions>
   <configuration>
       <outputDirectory>${project.build.directory}/jnlp</outputDirectory>
        <mainClass>com.example.Main</mainClass>
        <jnlp>
           <title>My Java Web Start Application</title>
           <vendor>MyCompany</vendor>
            <homepage>http://www.example.com</homepage>
           <description>My Java Web Start Application Description</description>
            <icon>http://www.example.com/icon.gif</icon>

                <menu/>

        </jnlp>
    </configuration>
</plugin>
