VSBuild step Failed after "SonarCloudPrepare" step in AZURE Pipeline

We have SonardCloud scan pipeline which has a VSBuild step run after a “SonarCloudPrepare” step.
This was all wokring till about 2 weeks ago.
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin\Roslyn\Microsoft.VisualBasic.Core.targets(41,5): error MSB6006: "vbc.exe" exited with code 255

We initially thought it was a problem with VS 2017 installation or a Nuget restore was not working. But after miuch struggle, we found that if we comment out the “SonarCloudPrepare” step, the pipeline will complete without problem. Here is the log of “SonarCloudPrepare” step:

Welcome to the community!

Please share verbose logs from the Scanner for .NET:

  • Add /d:"sonar.verbose=true" to the…
    • SonarScanner.MSBuild.exe or dotnet sonarscanner begin command to get more detailed logs
      • For example: SonarScanner.MSBuild.exe begin /k:"MyProject" /d:"sonar.verbose=true"
    • “SonarQubePrepare” or “SonarCloudPrepare” task’s extraProperties argument if you are using Azure DevOps
      • For example:
        - task: SonarCloudPrepare@1
              SonarCloud: 'sonarcloud'
              organization: 'foo'
              scannerMode: 'MSBuild'
              projectKey: 'foo_sonar-scanning-someconsoleapp'
              projectName: 'sonar-scanning-someconsoleapp'
              extraProperties: |
  • The important logs are in the END step (i.e. SonarQubeAnalyze / SonarCloudAnalyze / “Run Code Analysis”)
