When integrating Clover reporting to a job, after the job has successfully built and Clover reports are generated, when clicking on the Job Name link in a view, the Coverage Report link located on the left side of the page (URL example: http://SERVERNAME/view/Testing/job/JOBNAME/clover/) does not contain the build number and therefore when you click the link you get a page with 404 error:
HTTP Status 404 -
type Status report
message
description The requested resource () is not available.
Apache Tomcat/6.0.24

navigating down to the specific build and then to the Clover Coverage Report link gets you to the proper pages.

The Generate an historical report and Generate a jwon report are checked within the Automatically record and report Clover Coverage in the job configuration. A proper license is entered. As well as the Publish Clover Coverage Report is manually configured correctly.
