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

Question

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'
}
}
}
}

Answer 1

Please check whether Java is available on the system where SonarQube Scanner is running.
Another thing you can try is:
Go to SonarQube Scanner Directory -> Go to bin -> chmod +x sonar-scanner
