MSBuild 中的嵌套目标批处理？

Question

我想对每个 DeploymentTarget 执行一个操作，其中每个 ProjectsForDeployment 可以有超过 1 个。我知道如果每个 ProjectsForDeployment 只有 1 个 DeploymentTarget child，则目标批处理会起作用 - 但如果有多个 children 会怎样？是否仍然可以运行 ProcessDeployableObject 针对 A1/A2/B1/B2 4 次，同时保持对兄弟姐妹和 parent 的引用？

谢谢！

要运行四次，你应该写四项而不是两项。

在您这边，DeploymentTarget A2 将被 A1 覆盖，因为它们在同一项目下。

要解决它，您必须将它们分开，这更像是一次一个 CSProj 运行 DeploymentTarget。当您使用 msbuild 命令行构建项目时，每个命令都应该适用于一个配置和平台。

使用这个：

<ItemGroup>
    <ProjectsForDeployment Include="/src/A/A.csproj" >
      <DeploymentTarget>A1</DeploymentTarget>
      <OtherMetadataWeNeed>Metadata</OtherMetadataWeNeed>
    </ProjectsForDeployment>
 
    <ProjectsForDeployment Include="/src/A/A.csproj" >
      <DeploymentTarget>A2</DeploymentTarget>
      <OtherMetadataWeNeed>Metadata</OtherMetadataWeNeed>
    </ProjectsForDeployment>


    <ProjectsForDeployment Include="/src/B/B.csproj" >
      <DeploymentTarget>B1</DeploymentTarget>    
      <OtherMetadataWeNeed>Metadata</OtherMetadataWeNeed>
    </ProjectsForDeployment>

    <ProjectsForDeployment Include="/src/B/B.csproj" >
      <DeploymentTarget>B2</DeploymentTarget>    
      <OtherMetadataWeNeed>Metadata</OtherMetadataWeNeed>
    </ProjectsForDeployment>
  </ItemGroup>
