JaCoCo report shows 0% coverage for Blu Age modernized application

Question

When trying to run JaCoCo on my Blu Age modernized application (CardDemo), I get 0% coverage after navigating in the online application screens. I found a weird line when looking at the execution log of JaCoCo:
Classes in bundle 'Entities Layer' do not match with execution data. For report generation the same class files must be used as at runtime.

Accepted Answer

JaCoCo uses a value called “classId” to compare java classes used at runtime and at analysis time. If these classes are different, the classId values are different, and JaCoCo does not compare them, thus the 0% coverage.

You can check the Blu Age L3 Workshop for CardDemo to help you with fixing the 0% coverage you observe, because it depends on your own configuration.
