是否获取MSBuild以将文件输出到日志？

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）能够获取它

如何让MSBuild将文件内容转储到输出？

您应该能够在构建脚本中执行类似的操作（请注意，我正在使用cygwin附带的cat命令输出文件内容）。根据您希望项目在生成过程中运行的时间，可以将目标更改为任何适当的值：

<Target Name="AfterGet">
    <Exec Command="cat your_file" />
</Target>

如果您需要在服务器上安装cygwin，您可以获得它。我不知道有哪个本机dos命令可以回送文件内容，但可能有一个。

dos命令可以回送文件内容

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

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

如果您知道写入文件的位置，可以使用该任务，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>

这里重要的一点（我不知道）是Exec总是（？）使用CMD.EXE，这意味着内置命令（如

type

）和重定向在

内部工作。对于linux“cat”，请使用windows“type”
