When viewing coverage as a top level project, it is possible to view the source code highlighted with coverage. If a folder is used (or multiple levels of folder), then the plugin reports not being able find the source code to display.
We have used the same project just moved to a folder and then the source is not visible.
The source can be viewed locally, but then the project have to be cloned and built locally.
With the folder plugin, there are multiple /job/ entries (one per folder) which could be confusing the resolving of the link in CoverageResult.java
