The current Maven jobs in Jenkins version 2.107.3 seems to create modules in the job directory. For example:

For a maven job name test_jira_integration, the job directory actually has modules directory

/var/lib/jenkins/jobs/Test/jobs/test_jira_integration/modules/com.xxxx$xxxxx

This is the error output by Jenkins log:

Jun 02, 2018 12:25:46 PM org.jenkinsci.plugins.JiraTestResultReporter.JiraUtils log

INFO: No configs found for project Test/test_jira_integration/com.xxxx:xxxxx

The config Jenkins use to build is actually inside /var/lib/jenkins/jobs/Test/jobs/test_jira_integration/modules/com.xxxx$xxxxx folder.

The reason why it saids config not found is because your code uses a separate json file (JiraIssueJobConfigs.json) for the plugin configurations instead of config.xml. This file is not copied by Jenkins into the Maven modules folders before each build job.

One possible solution is to read from the RootProject folder. The diff below is tested to work in our environment, but need full test and code review.
