Yahoo.Yui.Compressor.Build.MsBuild.dll。无法加载文件或程序集的Yahoo.Yui.Compressor

Question

我使用Yahoo.Yui.Compressor.Build.MsBuild来压缩css和javascript文件。我已经安装了XML2.2，Yahoo.Yui.Compressor.Build.MsBuild文件的格式是

     <?xml version="1.0" encoding="utf-8" ?>
<Project xmlns="http://schemas.microsoft.com/developer/MsBuild/2003">
  <UsingTask
      TaskName="CompressorTask"
      AssemblyFile="..\..\lib\yui\Yahoo.Yui.Compressor.Build.MsBuild.dll" />


  <PropertyGroup>
    <JavaScriptOutputFile Condition=" '$(JavaScriptOutputFile)'=='' ">..\scripts-min\myfile.min.js</JavaScriptOutputFile>
  </PropertyGroup>


  <Target Name="MyTaskTarget">

    <ItemGroup>

<JavaScriptFiles Include="$(SourceLocation)..\scripts\myfile.js"/>

</ItemGroup>
<CompressorTask
    CssFiles="@(CssFiles)"
    DeleteCssFiles="false"
    CssOutputFile="$(CssOutputFile)"
    CssCompressionType="YuiStockCompression"
    JavaScriptFiles="@(JavaScriptFiles)"
    ObfuscateJavaScript="True"
    PreserveAllSemicolons="False"
    DisableOptimizations="Nope"
    EncodingType="Default"
    DeleteJavaScriptFiles="false"
    LineBreakPosition="-1"
    JavaScriptOutputFile="$(JavaScriptOutputFile)"
    LoggingType="ALittleBit"
    ThreadCulture="en-au"

            />
</Target>

</Project>

当我构建代码时，它会显示下面的错误

  Error 18  The "CompressorTask" task could not be loaded from the assembly D:\Projects\YUI\..\..\lib\yui\Yahoo.Yui.Compressor.Build.MsBuild.dll. Could not load file or assembly 'Yahoo.Yui.Compressor, Version=2.2.0.0, Culture=neutral, PublicKeyToken=null'or one of its dependencies. The system cannot find the file specified. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask.

我也遇到了同样的问题...

看起来Yahoo.Yui.Compressor.dll需要和Yahoo.Yui.Compressor.Build.MsBuild.dll在同一个目录中。其他依赖项可能也是如此，比如EcmaScript.NET.dll和Iesi.Collections.dll。

您可以将内容移动到\lib\yui\目录中，使它们并排放置，也可以引用bin文件夹中的程序集。

如果您决定引用bin文件夹中的程序集，则可能必须使用生成后事件来触发压缩，而不是使用生成前事件。
