Error while running sonarqube from Jenkins as sonar-scanner Permission denied

Below is the error from Jenkins console output:

+ sonar-scanner -Dsonar.login=**** -Dsonar.projectBaseDir=.
/var/lib/jenkins/workspace/Mtr-Pipeline_develop@2@tmp/durable-0080bcff/script.sh: 1: /var/lib/jenkins/workspace/Mtr-Pipeline_develop@2@tmp/durable-0080bcff/script.sh: sonar-scanner: Permission denied

I have setup the token and pasted the key in t-m-sonar-login variable in Jenkins global credentials.But I dont think it should be the keys causing `permission denied error. Can someone provide some pointers to look into the issue.

stage('SonarQube scan') {
    agent {
        dockerfile { filename 'sonar/Dockerfile' }
    }
    steps {
        withCredentials([string(credentialsId: 't-m-sonar-login', variable: 'SONAR_LOGIN')]) {
            script {
                unstash 'coverage'
                unstash 'testResults'
                sh 'sonar-scanner -Dsonar.login="$SONAR_LOGIN" -Dsonar.projectBaseDir=. || true'
            }
        }

    }
}
