    I’m trying to import Code Coverage data & I’m getting an error that the line numbers don’t match the files.
    We use NCrunch to run the unit tests & it outputs a OpenCover xml file. The NCrunch team have confirmed the OpenCover file looks right (OpenCover report - Daily Usage Issues - NCrunch Forum), yet Sonar throws an error. The error isn’t limited to just this file, it can be whatever file Sonar decides to start with.

It feels like an off-by-one error.

  • Potential workaround

Do not share screenshots of logs – share the text itself (bonus points for being well-formatted)!

Hi @simongh,

Thanks a lot for your feedback. Would it be possible to create a reproducer for us? If not, would it be possible to share the code file and the generated coverage?

Thanks,
Costin

let me see what I can do. I’m sure I can find a file without anything we can’t share in it

Hello @simongh

In addition, could you please share the debug logs with us?

Share the Scanner for .NET verbose logs

  • 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
    inputs:
      SonarCloud: 'sonarcloud'
      organization: 'foo'
      scannerMode: 'MSBuild'
      projectKey: 'foo_sonar-scanning-someconsoleapp'
      projectName: 'sonar-scanning-someconsoleapp'
      extraProperties: |
        sonar.verbose=true
  • The important logs are in the END step (i.e. SonarQubeAnalyze / SonarCloudAnalyze / “Run Code Analysis”)
