execute $mvn clean verify sonar:sonar Times error. I connected to a remote sonarqube server and configured it in the pom file to see why localhost/0:0:0:0:0:0:0:1:9000 is displayed in the error reported.

sonar-maven-plugin and sonar remote servers are also configured, as shown below:

$ mvn sonar:sonar -Dsonar.host.url=http://192.168.12.87:9009 -Dsonar.login=*
