编译 Java Play 应用程序时出错，找不到模板参数

Question

我正在尝试将现有的 .NET MVC 应用程序移植到 Java Play。此应用程序使用 ASP 母版页，我试图通过使用 Play 模板复制此概念。

我已按照此处的文档进行操作：https://www.playframework.com/documentation/2.5.x/JavaTemplateUseCases

如果我copy/paste这个例子，一切都会编译。但出于某种原因，替换我自己的参数会导致此错误...

turkish:myApp adam$ ./bin/activator clean compile

如示例所示，我已在第一行声明（？）我的参数：

@(AdditionalPageIncludes: Html)(SubNavigation: Html)(SectionTitle: Html)(TableOfContentsPlaceHolder: Html)(ArticlePlaceHolder: Html)

我昨天在一个类似的页面上经历了这个确切的过程，并最终以某种方式编译了所有内容。它似乎是先编译视图，然后运行通过激活器进行干净编译的某种组合。这在今天似乎不起作用。

似乎每个项目构建后都遗留下来了很多工件，这就是为什么我每次都运行干净编译（这需要永远）。我有一种感觉，我只是不了解这些 templates/parameters 应该如何工作。

这是在使用 Java/Scala/Play 时使用参数定义模板的正确方法吗？似乎它期望使用此参数而不是声明它。

编辑：

这是正确编译的模板(views/Shared/PublicMain.scala.html):

@(AdditionalPageIncludes: Html)(MainContent: Html)

<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <meta name="description" content="" />

    @MainContent

这是编译失败的模板(views/Shared/DocumentationMain.scala.html):

我想我发现了问题...因为我正在迁移一个现有的应用程序，所以我一直在将原始文件复制到新的项目文件夹中并做一些大量的 find/replace 事情。我尝试在 IntelliJ 中创建一个全新的文件，添加我需要的模板参数，一切都正确编译。

看来您必须直接从 IDE 添加新文件才能在幕后 link 一起制作一些东西。否则它似乎无法找到要编译的源代码。这对我来说仍然没有任何意义，但至少我的模板现在正在编译。
