Make sure that you correctly specify directory with classes during generation of report. Make sure that you don't have warnings during generation of report. Make sure that exact same class files are used at runtime and during generation of report - see http://www.jacoco.org/jacoco/trunk/doc/classids.html for more details, in particular: How can I detect that I have a problem with class ids? The typical symptom of class id mismatch is classes not shown as covered although they have been executed during the test. This situation can be easily detected e.g. in the HTML report: Open the *Sessions* page with the link on the top-right corner. You see a list of all classes where execution data has been collected for. Find the class in questions and check whether the entry has a link to the corresponding coverage report page. If the entry is not linked this means there is a class id mismatch between the class used at runtime and the class provided to create the report.
