SonarQube Test Failing Consistently

Question

I have tried to build a webapp application, test using sonarqube, deploy to nexus as artifactory, build docker image and push to a docker repository and finally deploy to tomcat. However, my script doesn't run past Sonarqube before pulling up this error. I would appreciate insight into resolving this problem.

Please find below my script and the corresponding error log.
