GWT 2.5.1 mvn 安装错误"重新绑定结果<class>必须是类"

Question

问题：我在使用 gwt-maven-plugin 构建的 GWT 2.5.1 项目上运行 mvn gwt：compile，并得到错误重新绑定结果必须是我拥有的所有扩展 CssResource 的类中的类。

此类是其中之一：

public interface MainShellStyle extends CssResource{
    public static final MainShellStyle INSTANCE =  GWT.create(MainShellStyle.class);
    public String txtCompanyName();
    public String txtCompanySlogan();
    public String txtCompanyMessage();
    public String topRibbon();
    public String mainMenu();
    public String btnEditContacts();
    public String btnEditGuestBook();
    public String btnEditPictures();
    public String btnEditHome();
}

我的pom.xml如下：

<!-- Dependecies --!>
<build>
        <!-- Generate compiled stuff in the folder used for development mode -->
        <outputDirectory>${project.build.directory}/${project.build.finalName}/WEB-INF/classes</outputDirectory>
        <!-- Plugins -->

            </plugin>
        </plugins>
        <!-- End Plugins -->
    </build>

这是我第一次编译GWT项目。我做错了什么？

谢谢。

您无法GWT.create() CssResource接口，您必须从您将GWT.create() ClientBundle引用它。与 CSS 文件的关联是通过 ClientBundle 方法建立的。

见 http://www.gwtproject.org/doc/latest/DevGuideClientBundle.html
