    ERROR:
    ERROR: Re-run SonarQube Scanner using the -X switch to enable full debug logging.

I don't know what to do, I've try many things that i've seen here but nothing is working unfortunately..

Answer 1

I've got this too, but I was using gradle to run sonar for sonarcloud.io, once I turned on --stacktrace and --debug it was clear from the logs I was getting this error because my credentials did not get recognized by the sonar server. I've double checked them and after changing to the correct credentials all went fine.

So besides trying to run it with -X as suggested to get more info, I'd suggest you also try to double check your credentials.
