获取MSBuild将文件输出到日志？

Question

我有一个输出到文件的程序.我正在从MSBuild项目运行它.我希望将此输出写入StdOut,以便我们的构建代理(TeamCity)可以将其输出.

如何让MSBuild将文件内容转储到输出？

Answer 1

dos命令类型可以.

<Target Name="ExecProgramAndOutputToStdOut">
  <Exec Command="YourProgram.exe"/>

  <Exec Command="type output_file"/>
</Target>

Answer 2

如果您知道写入文件的位置,则可以使用ReadLinesFromFile任务,然后记录所有消息.例如,看看下面的项目文件.

<Project DefaultTargets="Demo" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <PropertyGroup>
        <_File>$(MSBuildProjectFullPath)</_File>
    </PropertyGroup>
    <Target Name="Demo">
        <ReadLinesFromFile File="$(_File)">
            <Output ItemName="_FileContents" TaskParameter="Lines"/>
        </ReadLinesFromFile>

        <Message Text="File contents: '$(MSBuildProjectFullPath)'"/>
        <!-- Prints one after another with a ';' between each line -->
        <Message Text="@(_FileContents)"/>

        <Message Text="-------------"/>
        <!-- Prints one after another with each on its own line -->
        <Message Text="%(_FileContents.Identity)"/>
    </Target>
</Project>

此文件读取当前文件(via $(MSBuildProjectFullPath))并将结果打印到控制台.我已经展示了如何以两种方式打印出来,一个显示了; 分开的值,另一个在它自己的一行上显示一个.请注意,ReadLinesFromFile任务不会保留前导(甚至可能是尾随)空格.

这是执行Demo目标时的结果.
