多设备混合应用程序+ webessentials：捆​​绑两个css文件会出错

Question

我使用带有webessentials的多设备混合应用程序CTP 2并尝试两个捆绑两个css文件。它给出了以下错误：

16-8-2014 22:58:19: System.NullReferenceException: Object reference not set to an instance of an object.
   at MadsKristensen.EditorExtensions.FileHelpers.RelativePath(String absolutePath, String relativeTo)
   at MadsKristensen.EditorExtensions.BundleDocument.GetRelativePath(String file, String root)
   at MadsKristensen.EditorExtensions.BundleDocument.<>c__DisplayClass5.<WriteBundleRecipe>b__2(String file)

   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
   at MadsKristensen.EditorExtensions.BundleFilesMenu.<MakeBundleAsync>d__27.MoveNext()

创建了文件 Mybundle.css.bundle 但是：

1. 是空的
2. 未包含在项目中

我在项目中加入了 Mybundle.css.bundle ，并添加了所需的配置如下：

<?xml version="1.0" encoding="utf-8"?>
<bundle xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://vswebessentials.com/schemas/v1/bundle.xsd">
  <settings>
    <!--Determines if the bundle file should be automatically optimized after creation/update.-->
    <minify>true</minify>
    <!--Determin whether to generate/re-generate this bundle on building the solution.-->
    <runOnBuild>true</runOnBuild>
    <!--Use absolute path in the generated CSS files. By default, the URLs are relative to generated bundled CSS file.-->
    <adjustRelativePaths>true</adjustRelativePaths>
    <!--Specifies a custom subfolder to save files to. By default, compiled output will be placed in the same folder and nested under the original file.-->
    <outputDirectory />
  </settings>
  <!--The order of the <file> elements determines the order of the files in the bundle.-->
  <files>
    <file>/css/index.css</file>
    <file>/css/stylesheet.css</file>
  </files>
</bundle>

编译或保存其中一个css文件不会触发捆绑。

多设备混合应用CTP 2 和 WebEssentials 一起工作？

Answer 1

您应该在https://github.com/madskristensen/WebEssentials2013

向Mads Kristensen报告这些错误

Answer 2

打开https://github.com/madskristensen/WebEssentials2013/issues/1429，因为在使用适用于Visual Studio CTP2.0的多设备混合应用程序上使用Web Essentials 2013捆绑css时也遇到类似错误

Answer 3

请参阅此问题的答案：Why is Visual Studio 2013 crashing when I try to create/open a Multi-Device Hybrid Apps application?

将多设备混合应用程序CTP2和WebEssentials一起安装时会出现问题。您需要禁用WebEssentials或切换到WebEssentials的每晚构建。
