        stage('Build') {
            steps {
                sh '/opt/apache-maven-3.6.3/bin/mvn clean package'
                echo 'Hello World'
            }
        }

        stage('Test') {
            steps {
                sh '/opt/apache-maven-3.6.3/bin/mvn sonar:sonar -Dsonar.projectKey=studentapp-ui -Dsonar.host.url=http://52.66.207.203:9000 -Dsonar.login=75df1c9e34a0449ff40447fe08bd4b8424396605'
                echo 'Testing done'
            }
        } 

        stage('Deploy') {
            steps {
            echo 'Deployed !!!!!!!!'
          }
    }
}

4.If your facing error running sonarqube then change java version to jdk11-bellsoft

Install java-jdk-bellsoft to handle error

yum install wget epel-release -y
yum install java -y
wget https://download.bell-sw.com/java/11.0.4/bellsoft-jdk11.0.4-linux-amd64.rpm
rpm -ivh bellsoft-jdk11.0.4-linux-amd64.rpm

change java jdk
