SonarQube doesn't show any results

Question

I don't know why sonarqube isn't showing any resuls while running sonar-scanner and even mvn clean verify sonar:sonar and everything is successfully but with no results.

this is my configuration:

sonar.host.url=http://localhost:9000
sonar.projectKey=releveproject
sonar.projectName=releveproject
sonar.java.binaries=**/**target/classes
sonar.login=admin
sonar.password=1234
