      I cannot build a windows service .NET Classic (v4.6.1) project that references ASP.NET Core libraries (for REST API functionality)

      Pipeline code:

      bat "\"${tool 'MSBuild 2017'}\" /p:Configuration=Release /p:Platform=\"${targetPlatform}\" /p:TargetFrameworkVersion=${dotnetVersion} /p:OutputPath=\"${WORKSPACE}\\${buildOutputPath}\""

      Jenkins runs this command

      "C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0\Bin\MSBuild.exe" /p:Configuration=Release /p:Platform="x86" /p:TargetFrameworkVersion=v4.6.1 /p:OutputPath="E:\Jenkins\workspace\repo_name_branch\output"

      I get the following error:

      So I get an Environment variable name or value is too long. error from MsBuild.

      The funny thing is, that running the same command in cmd terminal on the very same computer works. Only under Jenkins seems the build not working. I tried to run Jenkins as a windows service (under SYSTEM user), or just as a regular process under my own user account. Both times this fails for the same reason.
