如何让GroovyDoc正确记录具有泛型类型参数的返回类型？

Question

我有一个ant任务，可以生成我的Maven pom文件中定义的GroovyDoc。除了返回类似这样的方法的方法文档之外，一切看起来都很棒：

    List<WebElement> are documented with List as the return type. The generic type  parameter is totally missing:

    List    getAccountsMenuOptions()

    Gets the list of links that are currently displayed in the account selector menu

    I expected something like this:

    List<WebElement>    getAccountsMenuOptions()

    Gets the list of links that are currently displayed in the account selector menu

这就是我定义任务的方式：

     <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-antrun-plugin</artifactId>
        <version>1.7</version>

           <execution>
              <id>groovydoc</id>
              <phase>package</phase>
              <goals>
                 <goal>run</goal>
              </goals>
              <configuration>
                 <target>
                    <taskdef name="groovydoc"
                     classname="org.codehaus.groovy.ant.Groovydoc" 
                     classpathref="maven.compile.classpath"/>

                    <groovydoc destdir="target/groovydoc"
                     sourcepath="src/main/groovy" use="true"
                     windowtitle="Epiphany"
                     doctitle="Epiphany">
