Hi Mark, Need some help on this. I want to it using the ReportGenerator.java provided in the examples. I am not getting how to restrict the reports to specific classes? Is it a vice idea to collect all required .java files in one folder say mysource and then give it as a sourceDirectory? Do I need to maintain the structure like com/jacoco/examples... etc?
