sonar.projectKey=decodingdevops
sonar.projectName=devops
sonar.projectVersion=1.0
sonar.sources=/var/lib/jenkins/workspace/$JOB_NAME/my-app/src
sonar.java.binaries=**/target/classes

sonar.sources=/var/lib/jenkins/workspace/$JOB_NAME/<PROJECT_NAME>/src
Here project name is nothing but directory name of your project in git hub or bit bucket or SCM.

save the jobs that's all we have successfully integrated sonarqube with jenkins. build the job you can see the code analysis in sonarqube server.

if you are using amazon ec2 instances you have to enable the 9000 port of sonarqube server from jenkins server ip otherwise jenkins cannot reach sonarqube server. now we have successfully done sonarqube integration with Jenkins for code analysis.
