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

    C:\Users\remy.fischer\Desktop\NetBeansProjects\NetBeansProjects\BinPacking\sonar-scanner-3.0.3.778-windows\bin>

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.

Answer 2

I had the same exact error when trying to trigger sonar analysis from within Jenkins, after houres of searching, i figured out that the problem was related to path defintion.

In your sonar-project.properties file or in SonarQube configuration section within your project configuration section, make sure that the property sonar.sources defines a path using forward slashes (/)

the property must be defined like this : sonar.sources=D:/software/jenkins/JenkinsHome/workspace/test_jenkins

and NOT like this : sonar.sources=D:\software\jenkins\JenkinsHome\workspace\test_jenkins
