缺少 grails 引导文件上传插件的资源？答案

【问题标题】：Missing resources for grails bootstrap file upload plugin?缺少 grails 引导文件上传插件的资源？

【问题描述】：

我正在尝试在我的 grails 应用程序 (http://grails.org/plugin/bootstrap-file-upload) 中使用 grails 引导文件上传插件。

我的 grails 版本是 2.2.1。插件版本为 2.1.2。插件安装成功。我还安装了 twitter-bootstrap -3.1.1.3 插件。我正在尝试使用上传插件的 UI 风格。需要包含哪些资源。插件的文档没有谈论它。

目前我包括以下内容。

<r:require module="bootstrap"/>
<r:require module="bootstrap-file-upload"/>

但是我收到以下错误。

        compile ":twitter-bootstrap:3.1.1.3"

        //target
        build ":tomcat:$grailsVersion"
    }
}

有人知道如何解决这个问题吗？

【问题讨论】：

请发布您的 BuildConfig.groovy 内容。
添加了 BuildConfig.groovy 内容

标签： jquery twitter-bootstrap grails jquery-file-upload

【解决方案1】：

请仔细检查您的布局文件（默认为 main.gsp）是否有两个 <r:layoutResources/> 标签，一个在 <head> 部分，一个在 <body> 部分的末尾。

【讨论】：

当我删除问题中提到的插件时，错误消失了。
