这是非常similar to this question,除了问题,除了在修复VS2013之后MSBUILD上存在问题。即使编译器和链接器认为项目是最新的,构建后事件仍在运行。
有关如何阻止构建后事件在此处运行的任何想法?

此功能内置于MsBuild for .Net项目(在Microsoft.Common.Targets中搜索PostBuildEvent,另见here),这是一个简化版本。原则是在构建之前获取输出文件的时间戳,在构建之后获取另一个时间戳,然后比较它们。如果它们是相同的,显然没有真正构建的东西。这个逻辑有一个可能的插入点的镜像,在这里我只选择了链接阶段应该做得很好:
<Target Name="GetTimeStampBeforeLink" BeforeTargets="Link">
<ItemGroup>
<ProjectOutputFiles Include="$(TargetPath)" />
</ItemGroup>
<PropertyGroup>
<OutputTimeStampBeforeLink>%(ProjectOutputFiles.ModifiedTime)</OutputTimeStampBeforeLink>
</PropertyGroup>
</Target>
<Target Name="GetTimeStampAfterLink" AfterTargets="Link">
<PropertyGroup>
<OutputTimeStampAfterLink>%(ProjectOutputFiles.ModifiedTime)</OutputTimeStampAfterLink>
<OutputFilesModified Condition="'$(OutputTimeStampBeforeLink)' != '$(OutputTimeStampAfterLink)'">True</OutputFilesModified>
</PropertyGroup>
</Target>
您可以将此代码直接插入到项目文件中,但更好的方法是将其保存在单独的文件中,以便您可以通过将其导入到任何您想要的位置来重复使用if。您还可以通过添加到ProjectOutputFiles
ItemGroup来添加要检查的文件。
现在剩下的就是禁用PostBuildEvent。 MsBuild已经有了一个机制,因为postbuild事件调用是以一个名为PostBuildEventUseInBuild
的属性为条件的,因此如果未修改输出文件,我们将其设置为false:
<Target Name="DisablePostBuildEvent" AfterTargets="GetTimeStampAfterLink">
<PropertyGroup>
<PostBuildEventUseInBuild Condition='"$(OutputFilesModified)' != 'True'">false</PostBuildEventUseInBuild>
</PropertyGroup>
</Target>

stjin的回答稍微简单一点:
<Target Name="DisablePostBuildEvent" AfterTargets="Link" BeforeTargets="PostBuildEvent">
<PropertyGroup>
<PostBuildEventUseInBuild Condition="'$(LinkSkippedExecution)' == 'True'">false</PostBuildEventUseInBuild>
</PropertyGroup>
</Target>
如果链接器实际执行,这只会执行post build事件。
