Sonar_scanner.bat having network trouble

SonarScanner 5.0.1.3006

  • Developer edition
  • Deployed via .zip
  • I am trying to achieve successful sonar_scanner.bat runs
  • I have tried using an empty port by changing the port number in sonar-scanner.properties

Hello. I have achieved successful build-wrapper builds in my Visual Studio project and I am trying to run sonar_scanner.bat within that project. I have run into the following error:

ERROR: Error during SonarScanner execution

I saw a similar topic about this error where someone had to kill a process on the default port (9000), but I changed the port to 8000 instead of killing the process that was using 9000.

#Configure here general information about the environment, such as SonarQube server connection details for example
#No information about specific project should appear here

#----- Default SonarQube server
sonar.host.url=http://localhost:8000

#----- Default source code encoding
#sonar.sourceEncoding=UTF-8

I have verified that 8000 is empty using the netstat command, so I’m not sure what to try now.
Any help/remediations would be greatly appreciated!

Hi,

Welcome to the community!

This means that the scanner wasn’t able to contact your SonarQube server

Normally when I see a localhost address in these messages, I think that no sonar.host.url was supplied, because the scanner defaults to a SonarQube address of http://localhost:9000. But your port here is 8000, so clearly you’ve supplied a URL.

Just where is your SonarQube instance hosted? Is it on the same machine that you’re running analysis from? (BTW, this is fine for initial evaluation, but not a good produciton setup.)
