  • what have you tried so far to achieve this

I’m trying to follow this guide: C/C++/Objective-C

When I execute:

sonar-scanner

I get this output:

Hey there.

  • Can you confirm that, for example, you can access SonarQube at this address in a web browser on the same machine you’re running the analysis? https://sonarqube.example.local
  • Can you try DEBUG level analysis and provide the logs? sonar-scanner -X

I tried to analyze again with -X option and the output said that credentials are wrong. Then I added username and password into sonar-project.properties and now I’m getting the following error:

This time it looks like everything might have worked just fine, and you’re facing a messy log issue we’ll fix with SonarQube v10.6.

Do you see your analysis on SonarQube?

5

Oh I’ve just noticed. The project was actually created in my Sonarqube dashboard.

But I guess I need to hustle a little more. Currently Sonarqube says only “The main branch has no lines of code.”

6

Sadly I can’t figure out this issue. Output from sonar-scanner seems reasonable, but I don’t understand why Sonarqube thinks the project has no lines of code.

7

Sharing the DEBUG scanner logs (sonar-scanner -X) here might help somebody help you!

I figured it out. I wasn’t paying close attention to the actual logs. I had to add the following settings:

sonar.branch.name=mybranch
sonar.scm.exclusions.disabled=true
sonar.filesize.limit=100

Finally after resolving the upload limit issue on the server side I got the code into SQ dashboard.
