MSBuild的消息輸出兩次

Question

我有以下目標：

<Target Name="SetBinariesLocationForTeamBuild"> 
    <!--We add the following location paths because TFS Team Build first copies to \sources and \binaries folders 
    rather than simply having the binaries in a \bin folder of the source folder 
    at this point the build will be at: C:\Builds\3\x.Int.MIS\SupportBTDF\Sources\x.Int.MIS\Dev\V1.0\Src\Solutions\MIS\x.Int.MIS.Deployment 
    so we need to go up 4 levels before going back down to binaries--> 
    <Message Text="Value of TeamBuild=$(TeamBuild)"/> 

    <Message Text="MSBuildProjectName: $(MSBuildProjectName)"/> 
    <Message Text="MSBuildStartupDirectory: $(MSBuildStartupDirectory)"/>

     </Schemas> 
    </ItemGroup>

    </ItemGroup> 

    <ItemGroup>

     <LocationPath>..\..\..\..\..\..\..\..\binaries\</LocationPath> 
     </Orchestrations> 
    </ItemGroup> 

    <ItemGroup> 
     <Transforms Condition ="'$(TeamBuild)' == 'True'" Include="x.Int.Transforms.dll">

    <Message Text="What is Schemas location path: %(Schemas.LocationPath)"/> 
    <Message Text="What is Pipelines location path: %(Pipelines.LocationPath)"/> 

    </Target> 

我從命令行傳入/ P運行項目：TeamBuild =真/噸：SetBinariesForTeamBuild。輸出讓我非常疑惑...

我想要位置路徑是8 .. \但它不是 - 任何想法爲什麼以及爲什麼打印兩次！

Answer 1

@（Schemas）和@（Pipelines）項目數組每個都獲得添加到其中的另一個項目元組，或者它們不能被打印出來。必須有另一個目標正在發生這種情況。如果您使用確切的命令行在項目上運行msbuild，那麼額外的目標必須是項目上的InitialTargets中的條目，否則使用BeforeTargets或AfterTargets引用指向上面目標中的目標。 。
