我目前正在创建我的第一个MSBuild脚本。
我有一个标签“文件夹”，它在给定的根路径中查找所有目录：
<?xml version="1.0" encoding="utf-8"?> <Project DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" ToolsVersion="4.0"> <Target Name="Build"> <PropertyGroup> <RootFolder>tmp</RootFolder> </PropertyGroup> <ItemGroup> <Folders Include="$([System.IO.Directory]::GetDirectories("$(RootFolder)"))"/> </ItemGroup> <Message Text="@(Folders -> '%(FullPath)\Bin\Debug\%(Filename)%(Extension).dll', ';')"/> </Target> </Project>这很完美。 我的问题是我只需要指定文件所在的目录。 我试过这样的条件
Condition="$([System.IO.File]::Exists("%(FullPath)\\Bin\\Debug\\%(Filename)%(Extension).dll"))"对于文件夹标签。
此脚本运行时没有任何错误，但我的列表为空。 为什么？
有没有其他解决方案来检查文件？
我使用此解决方案是因为它使用C＃而我是C＃开发人员。
<?xml version="1.0" encoding="utf-8"?> <Project DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" ToolsVersion="4.0"> <Target Name="Build"> <PropertyGroup> <RootFolders>tmp</RootFolders> </PropertyGroup> <GetFiles rootFolders="$(RootFolders)"> <Output PropertyName="Files" TaskParameter="Files" /> </GetFiles> <Message Text="$(Files)" /> </Target> <UsingTask TaskName="GetFiles" TaskFactory="CodeTaskFactory" AssemblyFile="$(MSBuildToolsPath)\Microsoft.Build.Tasks.v4.0.dll"> <ParameterGroup> <rootFolders ParameterType="System.String" Required="true" /> <files ParameterType="System.String" Output="true" /> </ParameterGroup> <Task> <Using Namespace="System" /> <Using Namespace="System.IO" /> <Using Namespace="System.Linq" /> <Code Type="Fragment" Language="cs"> <![CDATA[ Func<string, string> BuildFilePath = path => path + @"\Bin\Debug\" + Path.GetFileName(path) + ".dll"; var dirs = Directory.GetDirectories(rootFolders).Where(x => File.Exists(BuildFilePath(x))); files = string.Join("\n", dirs.Select(BuildFilePath)); ]]> </Code> </Task> </UsingTask> </Project>I currently create my first MSBuild-script.
I've a tag "Folders" that findes all Directories in a given root path:
<?xml version="1.0" encoding="utf-8"?> <Project DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" ToolsVersion="4.0"> <Target Name="Build"> <PropertyGroup> <RootFolder>tmp</RootFolder> </PropertyGroup> <ItemGroup> <Folders Include="$([System.IO.Directory]::GetDirectories("$(RootFolder)"))"/> </ItemGroup> <Message Text="@(Folders -> '%(FullPath)\Bin\Debug\%(Filename)%(Extension).dll', ';')"/> </Target> </Project>That works perfect. My problem is that I only need directories where the specified file exists. I tried a condition like that
Condition="$([System.IO.File]::Exists("%(FullPath)\\Bin\\Debug\\%(Filename)%(Extension).dll"))"for the folder tag.
This script runs without any error but my list is empty. Why?
Are there any other solutions to check for a file?
I used this solution because it uses C# and I'm a C#-developer.

AFAIK，就是执行Condition并检查整个项目声明（即<Folders ..>标签）。
我认为，您需要遍历集合（例如，使用目标/任务批处理）并检查文件是否存在于集合中的每个文件夹文件夹中。 然后，如果文件存在 - 将其包含在新的<FoldersFiletered>项集合中。
注意：我现在没有时间测试代码，但这是大致的想法：
<Target Name="FilterFolders" Inputs="@(Folders)" Outputs="%(FullPath)"> <ItemGroup> <FoldersFiltered Include="@(Folders->'%(FullPath)')" Condition="$([System.IO.File]::Exists("@(Folders->'%(FullPath)'\\Bin\\Debug\\YourFile.dll"))" /> </ItemGroup> </Target>AFAIK, the thing is Condition is executed and checked for the whole declaration of Items (i.e. <Folders ..> tag).
I think, you need to loop through the collection (e.g. using target/task batching) and check the file to exist in every single folder folder in the collection. Then if the file exists - include it in the new <FoldersFiletered> items collection.
NB: I don't have time to test the code now, but this is the idea roughly:
<Target Name="FilterFolders" Inputs="@(Folders)" Outputs="%(FullPath)"> <ItemGroup> <FoldersFiltered Include="@(Folders->'%(FullPath)')" Condition="$([System.IO.File]::Exists("@(Folders->'%(FullPath)'\\Bin\\Debug\\YourFile.dll"))" /> </ItemGroup> </Target>更多推荐
