Grails Asset Pipeline 导致服务器错误

【问题标题】：Grails Asset Pipeline causing server errorGrails Asset Pipeline 导致服务器错误
【发布时间】：2014-10-17 08:27:59
【问题描述】：

我创建了一个没有自定义控制器的 Grails 应用程序，我通过 Docker 使用 Tomcat 进行了部署。该应用程序在我的本地计算机上运行正常（run-app 和 run-war），但在我使用 Tomcat 部署时却不行。

我得到以下堆栈跟踪，请问知道原因吗？

【问题讨论】：

  • 你能发布 grails-app/views/layouts/main.gsp 吗？从堆栈跟踪来看，favicon.ico 似乎存在问题。您能否验证该文件也存在于您的项目中？
  • @JoshuaMoore 谢谢，favicon.ico 存在于 target/assets 目录中，但似乎没有被复制到 war 文件中。我在部署时将war文件复制到Tomcat webapps目录，我猜错误是由于服务器无法找到favicon.ico文件。你知道为什么war文件不包含assets目录吗？ github.com/bertramdev/asset-pipeline/wiki/… 声明：“在生产中，资产管道会在创建战争时编译您的资产。...然后将这个文件夹复制到您的战争文件中。”
  • 您的Config.groovy 中是否为grails.assets.excludes 定义了任何内容？您使用的是什么版本的 Grails 和资产管道插件？
  • @JoshuaMoore 非常感谢最初的提示，问题出在 Gradle 和 Grails 一起使用，详情如下。
  • 不客气。很高兴你把它整理好了。有时，只需要通过谈话就可以了。 chat.freenode.org 上的#grails 也是一个很好的地方（：

【解决方案1】：

啊，找到了。问题是该项目在部署时是由 Gradle Grails 插件构建的。他们的文档中有一个衬里 (Gradle Grails plugin)：

使用 Grails Gradle 插件绕过了普通的 Grails 应用程序 构建有利于 Gradle 的框架。这样做的后果是 不再咨询 BuildConfig.groovy 以获取存储库或 依赖信息。

因此，从 BuildConfig.groovy 中包含的插件将被忽略，它是使用 build.gradle 中定义的插件（不包括资产管道插件）构建的。因此，“grails run-war”创建的war文件与“gradle war”创建的不同。解压 2 ​​个 war 文件显示了结构上的差异。将依赖项从 BuildConfig.groovy 移至 build.gradle 意味着正确构建了 war 文件。

感谢@JoshuaMoore 的初步提示，这让我走上了正轨。
