VS2010自定义构建工具,用于生成.h文件
我正在尝试在 VS2010 中集成一个自定义构建工具,该工具从源文件生成 .h 文件。我已经为该步骤创建了 .xml、.targets 和 .props。 XML 大部分是从 MASM 文件复制粘贴的,并以以下内容结尾:
<ItemType Name="FOO" DisplayName="Foo compiler" />
<FileExtension Name="*.foo" ContentType="FOO" />
<ContentType Name="FOO" DisplayName="Foo compiler" ItemType="FOO" />
这将我所有的 .foo 文件映射到 .props 中定义的 Foo 编译器:
<?xml version="1.0" encoding="utf-8"?>
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<ItemGroup>
<PropertyPageSchema Include="$(MSBuildThisFileDirectory)$(MSBuildThisFileName).xml" />
<AvailableItemName Include="FOO">
<Targets>FooCompile</Targets>
</AvailableItemName>
</ItemGroup>
<UsingTask TaskName="FOO" TaskFactory="XamlTaskFactory" AssemblyName="Microsoft.Build.Tasks.v4.0">
<Task>$(MSBuildThisFileDirectory)$(MSBuildThisFileName).xml</Task>
</UsingTask>
<Target Name="FooCompile" BeforeTargets="$(FOOBeforeTargets)" AfterTargets="$(FOOAfterTargets)" Condition="'@(FOO)' != ''" Outputs="%(FOO.Outputs)" Inputs="%(FOO.Identity);%(FOO.AdditionalDependencies);$(MSBuildProjectFile)" DependsOnTargets="_SelectedFiles">
<Message Importance="High" Text="@(FOO)" />
<FOO Condition="'@(FOO)' != '' and '%(FOO.ExcludedFromBuild)' != 'true'"
CommandLineTemplate="%(FOO.CommandLineTemplate)"
OutputFileName="%(FOO.OutputFileName)"
Inputs="%(FOO.Identity)" />
</Target>
</Project>
当我编译我的项目时,它成功识别并编译我的 foo 文件:
1>FooCompile:
1> apa.foo
1>FooCompile:
1> banan.foo
1>ClCompile:
1> test.cpp
1> main.cpp
我的问题这就是为什么它为每个文件打印一次“FooCompile:”,而 ClCompile 却没有?有什么办法可以改变这个吗?
如果我更改 cpp 文件并构建,我还将为每个文件获得一次此输出,这是我想避免的:
1>FooCompile:
1>Skipping target "FooCompile" because all output files are up-to-date with respect to the input files.
1>FooCompile:
1>Skipping target "FooCompile" because all output files are up-to-date with respect to the input files.
I'm trying to integrate a custom build tool in VS2010 that generates a .h-file from a source file. I've created a .xml, .targets and .props for the step. The XML is mostly copy-pasted from the MASM-file and ends with:
<ItemType Name="FOO" DisplayName="Foo compiler" />
<FileExtension Name="*.foo" ContentType="FOO" />
<ContentType Name="FOO" DisplayName="Foo compiler" ItemType="FOO" />
This maps all my .foo files to the Foo compiler that's defined in the .props:
<?xml version="1.0" encoding="utf-8"?>
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<ItemGroup>
<PropertyPageSchema Include="$(MSBuildThisFileDirectory)$(MSBuildThisFileName).xml" />
<AvailableItemName Include="FOO">
<Targets>FooCompile</Targets>
</AvailableItemName>
</ItemGroup>
<UsingTask TaskName="FOO" TaskFactory="XamlTaskFactory" AssemblyName="Microsoft.Build.Tasks.v4.0">
<Task>$(MSBuildThisFileDirectory)$(MSBuildThisFileName).xml</Task>
</UsingTask>
<Target Name="FooCompile" BeforeTargets="$(FOOBeforeTargets)" AfterTargets="$(FOOAfterTargets)" Condition="'@(FOO)' != ''" Outputs="%(FOO.Outputs)" Inputs="%(FOO.Identity);%(FOO.AdditionalDependencies);$(MSBuildProjectFile)" DependsOnTargets="_SelectedFiles">
<Message Importance="High" Text="@(FOO)" />
<FOO Condition="'@(FOO)' != '' and '%(FOO.ExcludedFromBuild)' != 'true'"
CommandLineTemplate="%(FOO.CommandLineTemplate)"
OutputFileName="%(FOO.OutputFileName)"
Inputs="%(FOO.Identity)" />
</Target>
</Project>
When I compile my project it successfully identifies and compiles my foo files:
1>FooCompile:
1> apa.foo
1>FooCompile:
1> banan.foo
1>ClCompile:
1> test.cpp
1> main.cpp
My question is why does it print "FooCompile:" once for each file while the ClCompile doesn't? Is there any way to change this?
If I change a cpp file and build, I'll also get this output once for each file, which I want to avoid:
1>FooCompile:
1>Skipping target "FooCompile" because all output files are up-to-date with respect to the input files.
1>FooCompile:
1>Skipping target "FooCompile" because all output files are up-to-date with respect to the input files.

FooCompile 目标使用“目标批处理”,这会导致目标对为输出属性 %(Foo) 指定的数组中的每个项目迭代一次。另一方面,ClCompile 目标使用整个项目数组 @(ClCompile) 进行操作。
您可以更改记录器的详细程度以避免出现消息,指定 /v:minimal,但当然您也可能会过滤掉其他信息。
The FooCompile target is using "target batching" which causes the target to iterate once for each item in the array specified for the Outputs attribute, %(Foo). The ClCompile target on the other hand operates using the entire item array @(ClCompile).
You can alter the verbosity of the logger to avoid the messages, specify /v:minimal, but of course you may be filtering out other information as well.
