问题
I have a batch script that I want to call from an MSBuild project, and the documentation says I can't use output from the batch (either console / environment variables) in the MSBuild project.
Is there a workaround?
回答1:
You can redirect the output of the command to a file using "> output.txt" and read that into a variable.
<PropertyGroup>
<OutputFile>$(DropLocation)\$(BuildNumber)\Output.txt</OutputFile>
</PropertyGroup>
<Exec Command="dir > "$(OutputFile)"" />
<ReadLinesFromFile File="$(OutputFile)">
<Output TaskParameter="Lines" ItemName="OutputLines"/>
</ReadLinesFromFile>
<Message Text="@(OutputLines->'%(Identity)', '%0a%0d')" />
