我正在尝试在 MSbuild ( http://yuicompressor.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=22364 ) 中使用 YIUCompression DLL，但是当我运行 MSBuild 时，我不断收到以下错误：

输出：

目标构建：
开始 Css/Javascript 压缩...

The most common cause for this is because the path is incorrect or the file name is incorrect ... so please check your path and file names. Until you fix this up, I can't continue ... sowwy.

在项目“Millena-I.Build.proj”中完成构建目标“Build”。

完成建设项目“Millena-I.Build.proj”。

构建成功。C:\JSMinify\YIUCompressor\Millena-I.Build.proj(17,5): 错误：无法读取路径/文件 [C:\JSMinify\YIUCompressor\Test\disableButton.js] 的数据。最常见的原因是路径不正确或文件名不正确...所以请检查您的路径和文件名。在您解决此问题之前，我无法继续... sowwy.C:\JSMinify\YIUCompressor\Millena-I.Build.proj(17,5): 错误：值不能为空。C:\JSMinify\YIUCompressor\Millena-I.Build.proj(17,5)：错误：参数名称：值

以下是我的构建脚本：

<!-- Execute CompressorTask for each file in the list -->
<CompressorTask
   Condition="'%(JavaScriptFiles.Identity)' != ''"
   JavaScriptFiles="%(JavaScriptFiles.Identity)"
   ObfuscateJavaScript="FoSho"
   PreserveAllSemicolons="Yeah"
   DisableOptimizations="Nope"
   EncodingType="Default"
   DeleteJavaScriptFiles="true"
   JavaScriptOutputFile="%(JavaScriptFiles.Identity)"
   LoggingType="ALittleBit" />

我已授予文件夹和文件的全部权限（已删除只读）。令人惊讶的是，当构建失败时，我的文件完全空白！

我在上一个 ASP.NET 项目中使用了 Java 版本的 YUICompressor。它是否适合您，或者您只是对 .dll 文件感兴趣？以下是我的目标任务。

<Target Name="MinifyScripts" Condition="Exists('$(JAVA_HOME)')">        
    <YuiCompress Files="@(JavaScriptContent)" Type="JS" JavaHome="$(JAVA_HOME)" YUIHome="$(MSBuildStartupDirectory)\Resource\BuildTool\yuicompressor-2.4.1.jar" />
    <YuiCompress Files="@(CssContent)" Type="CSS" JavaHome="$(JAVA_HOME)" YUIHome="$(MSBuildStartupDirectory)\Resource\BuildTool\yuicompressor-2.4.1.jar" />
</Target>

这真的很简单。尝试使用它。
