the build wrapper link on https://docs.sonarqube.org/display/PLUG/Building+on+Windows uses localhost. obviously this doesn’t work.
This link assumes that you have installed SonarQube locally, and SonarQube will provide you the version of the build wrapper that is compatible with its own version.
If you have a non local SonarQube installation, replace
localhost:9000 by your server address & port.
