Delphi Projects are not getting built in parallel with MSBUILD

Mohammad Mohsin 1

I am trying to build Delphi independent projects in parallel by using the BuildInParallel parameter with /m switch but the projects are getting built sequentially.

While calling Delphi projects from proj file I was getting the error MSB4057: The target "Build" does not exist in the project and that gets resolved by using a batch file that will combine the lines of rsvars.bat and msbuild.exe.

The content of proj and batch file looks like this;

PROJ file content

<Target Name="TargetTest"> 

        <ItemGroup> 

            <TargetProjectsToBuild Include="$(ProjectDir)\Server\Common\lib.dproj"/> 

            <TargetProjectsToBuild Include="$(ProjectDir)\Server\XXXX server\Test1.dproj"/> 

            <TargetProjectsToBuild Include="$(ProjectDir)\Server\XXXX server\Test2.dproj"/> 

            <TargetProjectsToBuild Include="$(ProjectDir)\Server\XXXX server\Test3.dproj"/> 

            <TargetProjectsToBuild Include="$(ProjectDir)\Server\XXXX server\Test4.dproj"/> 

            <TargetProjectsToBuild Include="$(ProjectDir)\Server\XXXX server\Test5.dproj"/> 

        </ItemGroup> 

        <Exec Command="&quot;$(BatFilePath)\BuildDelphi.bat&quot; &quot;%(TargetProjectsToBuild.Identity)&quot; Release Win64 $(OutDir) Build $(SigningDelphiCert)" ContinueOnError="true"/> 

</Target>

Batch file content

call "C:\Program Files (x86)\Embarcadero\Studio\20.0\bin\rsvars.bat" 

MSBuild.exe %1 /p:BuildInParallel=true;Config=%2;Platform=%3;Outputfolder=%4;Certificate=%6 /t:%5 /m:2

There are 2 cores available on the agent

Hi @Mohammad Mohsin , welcome to Microsoft Q&A forum. Did you try to set the BuildInParallel property in PROJ file? And set -maxcpucount switch to a value great than 1? Please refer to this doc: BuildInParallel task parameter.

Hi @Tianyu Sun-MSFT , I tried using BuildInParallel in the PROJ file instead of executing it from a separate batch file and also called rsvars file before the MSBuild task but in that case, I am getting an error Build Target not found.

<MSBuild Projects="@(TargetProjectsToBuild)" BuildInParallel="true" Targets="Build" Properties="Configuration=Release;Platform=Win64;OutputPath=$(OutDir);OutDir=$(OutDir)" ContinueOnError="true"/>

Hi @Mohammad Mohsin , so does the output log in CMD/Developer Command Prompt/command line tool show something like 1>, 2> … x> and on node 1, on node 2 … on node x?

Hi @Tianyu Sun-MSFT , No all projects are getting executed on node 1 sequentially.

Hi @Mohammad Mohsin , may I ask if your projects are included in the same solution folder? And is there a .sln file in the solution folder?

Hi @Tianyu Sun-MSFT , Projects are included in different folders (i.e. subfolders are there). In the parent folder, we have the Embarcadero RAD Studio Project Group (.groupproj) file.

Hi @Mohammad Mohsin , though I did many tests, I still can’t reproduce this issue. Could you share complete steps with me to reproduce this issue? I may need to know how you configure Delphi environment and how you create Delphi projects.
