内容辅助对 eclipse 中的 joinfaces 组件不起作用

如何解决内容辅助对 eclipse 中的 joinfaces 组件不起作用

内容辅助和新的 xhtml 页面选项不适用于 joinfaces。 我正在关注 Example 中的示例项目。 我尝试了多种解决方案似乎没有任何效果。 无法创建新的 xhtml 页面，也无法获得 bean 类的内容帮助。 面向 Java 开发人员的 Eclipse IDE 2020-06。

 <h:outputText value="#{test.helloWorld.firstName}" />

# 之后什么都没有显示，但在 h 之后它显示了选项。

@Component
@ViewScoped
public class Test {
    
    @Getter
    @Setter
    public HelloWorld helloWorld;
    
    @postconstruct
    public void init() {
        helloWorld = new HelloWorld();
    }
    
    public String changePage() {
        return "success";
    }
    
    public void save() {
        System.out.println("Hello"+helloWorld.getFirstName()+helloWorld.getLastName());
    }

}
