And here is my sonar-project.properties in my github repository project root directory.

sonar.projectKey=my:project
sonar.projectName=Refrigerator-manager
sonar.projectVersion=1.0

sonar.sources=refrigeratior_manager

sonar.host.url=http://localhost:9000

Here is my jenkins system configuration for sonarqube

Here is my jenkins global tool configurations for sonarqube scanner

Here is my Jenkins project configuration for execute sonarqube scanner

I searched google for solve this problem few days but I can't find solution.

Solution

Is your sonarqube scanner running when you run you build from Jenkins ?? If not, it will throw the above message because jenkins is trying to listen to the port 9000 but nothing is there.
