Msbuild 如何将项目展平为属性？

如何将项目展平为属性

根据这一点，只需声明一个以项为值的属性即可

但我发现实际操作完全相反。使用MSBuild 4.0运行此项目时，指定目标

install

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <Import Project="$(Project-to-import)" Condition="'$(Project-to-import)' != ''" />

  <ItemGroup>
    <RuntimeProj    Include="C:\TEMP\Design.proj" />
    <DesigntimeProj Include="C:\TEMP\Run.dproj" />
  </ItemGroup>

  <PropertyGroup> <!-- Flatten out the items to properties. -->
    <RuntimeProj>@(RuntimeProj)</RuntimeProj>
     <!-- ^ This bit doesn't work. MS documentation is wrong? -->
    <DesigntimeProj>@(RuntimeProj)</DesigntimeProj>
  </PropertyGroup>

  <Target Name="install">
    <Message Text="Hello world!"/>
    <MSBuild Projects="$(MSBuildProjectFile)" Targets="BuildRunPackage"   
             Properties="Project-to-import=$(RuntimeProj)" />
    <MSBuild Projects="$(MSBuildProjectFile)" Targets="BuildDesignPackage"
             Properties="Project-to-import=$(DesigntimeProj)" />
  </Target>

  <Target Name="BuildRunPackage">
    <CallTarget Targets="Clean" /> 
    <CallTarget Targets="Build" /> 
  </Target>

  <Target Name="BuildDesignPackage">
    <CallTarget Targets="Clean" /> 
    <CallTarget Targets="Make" /> 
    <CallTarget Targets="Register" />
  </Target>
<.Project>

@（RuntimeProj）
@（RuntimeProj）

。。。返回一个错误

错误MSB4012:表达式“要导入的项目=@（RuntimeProj）”不能在此上下文中使用。项目列表不能与预期项目列表的其他字符串连接。请使用分号分隔多个项目列表

我不是很确定，但我想你们会遇到评估顺序的问题。 据我所知，在评估项目之前先评估属性（请参阅中的属性和项目评估顺序） 如果您可以尝试从“安装目标”下的“全局”移动属性组，则应该可以

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <Import Project="$(Project-to-import)" Condition="'$(Project-to-import)' != ''" />

  <ItemGroup>
    <RuntimeProj    Include="C:\TEMP\Design.proj" />
    <DesigntimeProj Include="C:\TEMP\Run.dproj" />
  </ItemGroup>


  <Target Name="install">
    <PropertyGroup> <!-- Flatten out the items to properties. -->
      <RuntimeProj>@(RuntimeProj)</RuntimeProj>
      <DesigntimeProj>@(RuntimeProj)</DesigntimeProj>
    </PropertyGroup>

    <Message Text="Hello world!"/>
    <MSBuild Projects="$(MSBuildProjectFile)" Targets="BuildRunPackage"   
             Properties="Project-to-import=$(RuntimeProj)" />
    <MSBuild Projects="$(MSBuildProjectFile)" Targets="BuildDesignPackage"
             Properties="Project-to-import=$(DesigntimeProj)" />
  </Target>

  <Target Name="BuildRunPackage">

  <Target Name="BuildDesignPackage">

是。这是方法。您必须在

中展平属性。是。这是方法。您必须在
