Travis build for Visual Studio Solutions project not working

I am trying to build a Visual Studios Project on Travis. I have tried a lot of configurations but I keep getting the MSB4019 error: The imported project “/Microsoft.Cpp.Default.props” was not found. Confirm that the expression in the Import declaration “/Microsoft.Cpp.Default.props” is correct, and that the file exists on disk.

Screenshot of the whole error:

This is the workflow:

- name: VS Project for Windows (Autotester Testing)
      if: env(USING_WINDOWS_SLN) = true
      solution: Team17/Code17/StartupSPASolution.sln
      language: csharp
      script: |
              msbuild /p:Configuration=Release StartupSPASolution.sln

Any suggestions on how to fix this?

It looks like whatever MSBuild variable is in the script before “/Microsoft.Cpp.Default.props” is not set. Can’t say anything more specific without seeing the build, so the following are guesses.


First, I don’t see os: windows and mono:/dotnet: – so it’s probable that you’re running the job in Linux with a default version of Mono installed while you probably want Windows with VS build tools.

To diagnose the problem properly, run MsBuild with diagnostic output and tracing and upload the trace log somewhere for examination – to find out which exact variable it is and how the stock logic tries to fill it (most probably, by consulting the registry for VS installation paths).
