Jenkins HMS upgrade test is not publishing results because JIRAService class is not found.

This error is happening on Jenkins when running the HMS upgrade tests.
The class used to publish the results is not found on any directory.

The problem is because the jenkins-execute-hms-test.sh is downloading the code to another directory.
