我试图按照书中的代码示例构建一个play2应用程序:我在创建一个具有以下定义的表单模板时遇到困难:@(productForm:Form [Product])

@main("Product Form") {
Product Form
@helper.form(action = routes.Products.save()) {
    

    
 Product (@productForm("name").valueOr("new"))
    @helper.inputText(productForm("wan"), '_label -> "EAN")
    @helper.inputText(productForm("name"), 'label -> "Name")
    @helper.textarea(productForm("description"), '_label -> "Description")
    
    
     Cancel 
    }
 }

我得到以下eclipse(我安装了scala ide插件)

Multiple annotations found at this line:
    - reference to Form is ambiguous; it is imported twice in the same scope by import play.data._ and 
 import play.api.data._

我应该忽略这条消息吗？play compile运行正常,但我没有从表单中获得任何输出.
