c# - 未找到 MSBuild 社区任务

Question

我有 MyLib 库项目以及几个示例。库和示例在同一个解决方案 MySolution 中。

在 MyLib 库项目中，我包含了 MSBuild 代码来压缩整个解决方案并复制到另一个目录以进行 Internet 发布。

<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
  <Import Project="$(MSBuildExtensionsPath)\MSBuildCommunityTasks\MSBuild.Community.Tasks.Targets" />
  <Target Name="AfterBuild" Condition="'$(Configuration)' == 'Release'">
    <PropertyGroup>
      <ReleasePath>C:\Users\Administrator\Projects\CA\Libraries\Api-DotNet\</ReleasePath>
      <ZipFile>C:\Users\Administrator\Projects\CA\WebProject\libraries\Api-DotNet.zip</ZipFile>
    </PropertyGroup>
    <ItemGroup>
      <LibraryFiles Include="$(ReleasePath)\**\*.*" Exclude="$(ReleasePath)\**\*.user;$(ReleasePath)\**\*.suo;$(ReleasePath)\Api.*;$(ReleasePath)\**\packages\**;$(ReleasePath)\**\Lib.Test\**;$(ReleasePath)\**\*.nuspec;$(ReleasePath)\**\*.nupkg;$(ReleasePath)\**\*nuget*;$(ReleasePath)\**\*internal*;$(ReleasePath)\**\*ReSharper*\**;$(ReleasePath)\**\.svn\**;$(ReleasePath)\**\obj\**;$(ReleasePath)\lib\bin\Debug\**;$(ReleasePath)\lib\bin\Publish\**;$(ReleasePath)\Example\**\bin\**;" />
    </ItemGroup>
    <Zip Files="@(LibraryFiles)" WorkingDirectory="$(ReleasePath)" ZipFileName="$(ZipFile)" ZipLevel="9" />
  </Target>  
</Project>

问题是，当用户下载库并在另一台计算机上运行时，编译器显示错误，即找不到导入库 MSBuild.Community.Tasks.Targets。我想在构建解决方案时从项目文件中排除 ZipAndCopy 代码。如何做到这一点？

将此 Condition 添加到 Import 和 Zip 元素:

Condition="Exists('$(MSBuildExtensionsPath)\MSBuildCommunityTasks\MSBuild.Commu‌​nity.Tasks.Targets')"

例如:

<Import Project="$(MSBuildExtensionsPath)\MSBuildCommunityTasks\MSBuild.Community.Tasks.Targets"
        Condition="Exists('$(MSBuildExtensionsPath)\MSBuildCommunityTasks\MSBuild.Commu‌​nity.Tasks.Targets')" />
