Story reports not being published via Hudson Plugin

When the jBehave/xUnit plugin kicks in after our stories have executed, it fails to copy the reports with the following error:

[xUnit] [INFO] - Starting to record.
[xUnit] [INFO] - Processing JBehave-3.x
[xUnit] [INFO] - [JBehave-3.x] - 3 test report file(s) were found with the pattern '*/jbehave/.xml' relative to 'C:\bin\hudson\hudson_home\jobs\ConvergencePilotIntegrationTests\workspace' for the testing framework 'JBehave-3.x'.
[xUnit] [ERROR] - The result file 'C:\bin\hudson\hudson_home\jobs\ConvergencePilotIntegrationTests\workspace\ConvergencePlayerManagementIntegrationTests\target\jbehave\BeforeStories.xml' for the metric 'JBehave' is empty. The result file has been skipped.
[xUnit] [WARNING] - All test reports are empty.
[xUnit] [INFO] - Check 'Failed Tests' threshold.
[xUnit] [INFO] - Check 'Skipped Tests' threshold.

I have confirmed that all xml files are indeed generated (see attached).
