Question

根据名录:

<ItemGroup>
  <Dirs Include="FooDir1" />
  <Dirs Include="FooDir2" />
</ItemGroup>

我如何能够得到一份所有分局的名单。

将这一清单与<代码>(实体)**”改为“,与任何内容不相符,并与<代码>(实体)***”改为“,然后与<代码>RelativeDir产生只包含档案的目录。

目前,我不得不使用C#:

<UsingTask TaskName="GetSubdirectories" TaskFactory="CodeTaskFactory"
    AssemblyFile="$(MSBuildToolsPath)Microsoft.Build.Tasks.v4.0.dll">
    <ParameterGroup>
        <Directories ParameterType="Microsoft.Build.Framework.ITaskItem[]" Required="true" />
        <SubDirectories ParameterType="Microsoft.Build.Framework.ITaskItem[]" Output="true" />
    </ParameterGroup>
    <Task>
        <Code Type="Fragment" Language="cs"><![CDATA[
            var result = new List<ITaskItem>();
            foreach (var dirItem in Directories) {
                foreach (var dir in Directory.GetDirectories(dirItem.ItemSpec, "*", SearchOption.AllDirectories)) {
                    if (dir.Contains(@".svn") || dir.EndsWith(@".svn")) continue;
                    result.Add(new TaskItem(dir));
                }
            }
            SubDirectories = result.ToArray();
        ]]></Code>
    </Task>
</UsingTask>

<GetSubdirectories Directories="@(Dirs)">
    <Output TaskParameter="SubDirectories" ItemName="SubDirs" />
</GetSubdirectories>

但我要知道,有没有一种更为容易的办法。

Answer 1

摘自“MSBuild Trickery”一书:

<Import Project="EnableAllPropertyFunctions.tasks" />

<Target Name="GetSubdirectories">
   <ItemGroup>
      <Dirs Include="$([System.IO.Directory]::
         EnumerateDirectories(
            `.Foo`,
            `*`,
            System.IO.SearchOption.AllDirectories))"
            />
   </ItemGroup>

   <Message Text="%(Dirs.Identity)" />
</Target>

你们需要首先通过确保环境变异的MSBuild PropertyFunctions被设定为价值1(即进口品的Ctasks文档所完成,并承担在线任务)来实现扩大的财产功能。

@(Dirs)一旦设立,你就可以用“消除”的特性加以过滤,以摆脱颠覆的夹子。

Answer 2

<CreateItem Include="$(OutputFolder)**.*">
  <Output TaskParameter="Include" ItemName="FilesInSubFolders" />
</CreateItem>

<RemoveDuplicates Inputs="@(FilesInSubFolders-> %(RelativeDir) )">
  <Output TaskParameter="Filtered" ItemName="SubDirs"/>
</RemoveDuplicates>

<Message Text="@(SubDirs)"/>

这将把所有直接的次重通道带入@(分流)。如果您改动Include=“$(OutputFolder)**.*>至Include=“$(Output Folder)***.*,则复数包括所有分数。

以完全自足的例子扩大布赖恩的答复:

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" DefaultTargets="GetSubdirectories">
  <UsingTask TaskName="SetEnvironmentVariable"
             TaskFactory="CodeTaskFactory"
             AssemblyFile="$(MSBuildToolsPath)Microsoft.Build.Tasks.v$(MSBuildToolsVersion).dll">
    <ParameterGroup>
      <Name ParameterType="System.String" Required="true" />
      <Value ParameterType="System.String" Required="true" />
    </ParameterGroup>
    <Task>
      <Using Namespace="System" />
      <Code Type="Fragment" Language="cs"><![CDATA[
        Environment.SetEnvironmentVariable(Name, Value);
      ]]></Code>
    </Task>
  </UsingTask>

  <Target Name="GetSubdirectories">
    <SetEnvironmentVariable Name="MSBuildEnableAllPropertyFunctions" Value="1" />
    <ItemGroup>
      <Dirs Include="$([System.IO.Directory]::EnumerateFiles( .Stuff ,  * , System.IO.SearchOption.AllDirectories))"/>
    </ItemGroup>
    <Message Text="%(Dirs.Identity)" />
  </Target>
</Project>

I got the UsingTask example from 页: 1
