Question

我有YUICompressor.NET，http://yuicompressor.codeplex.com/，配置为msbuild任务，它在我的开发机器上按预期工作。

当我将代码推送到AppHarbor时，我收到以下构建错误：

D:\temp\q2hapsex.50d\input\Projects\CroquetScores.Web\Build\YUICompressor.targets(21,9):
error MSB4062: The "CompressorTask" task could not be loaded from the assembly
D:\temp\q2hapsex.50d\input\Projects\CroquetScores.Web\Build\..\Bin\Yahoo.Yui.Compressor.MsBuildTask.dll.
Could not load file or assembly
'file:///D:\temp\q2hapsex.50d\input\Projects\CroquetScores.Web\Bin\Yahoo.Yui.Compressor.MsbuildTask.dll' 
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

通过更改YUICompressor.targets中的使用任务，我在http://support.appharbor.com/discussions/problems/3629-yuicompresoor-msbuild-task尝试了建议：

<UsingTask TaskName="CompressorTask" AssemblyFile="..\Bin\Yahoo.Yui.Compressor.MsBuildTask.dll" />

到

<UsingTask TaskName="CompressorTask" AssemblyFile="$(OutDir)Yahoo.Yui.Compressor.MsBuildTask.dll" />

我使用以下命令测试本地计算机上的设置：

msbuild AppHarbor.sln /property:Configuration=Release /property:OutDir=D:\temp\TestingAppHarbor\

但除路径信息外，它会导致相同的错误：

D:\Code\croquetscores.com\Projects\CroquetScores.Web\Build\YUICompressor.targets(21,9): 
error MSB4062: The "CompressorTask" task could not be loaded from the assembly
D:\Code\croquetscores.com\Projects\CroquetScores.Web\Build\Yahoo.Yui.Compressor.MsBuildTask.dll. 
Could not load file or assembly
'file:///D:\Code\croquetscores.com\Projects\CroquetScores.Web\Build\Yahoo.Yui.Compressor.MsBuildTask.dll'
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.

如果我用实际路径替换YUICompressor.targets中的$（OutDir），那么解决方案的构建没有错误。

我做错了什么？

Answer 1

我认为最好使用property functions。

<PropertyGroup>
    <YuiCompressorDir>$([System.IO.Path]::GetFullPath('$(MSBuildThisFileDirectory)..\Bin'))</YuiCompressorDir>
</PropertyGroup>
<UsingTask TaskName="CompressorTask" AssemblyFile="$(YuiCompressorDir)\Yahoo.Yui.Compressor.MsBuildTask.dll" />

您可以查看来自example项目的直播 ASP.NET Web Stack。

如何在YUICompressor.targets中使用$（OutDir）？
