Merged Jacoco Report is empty

[orcuns]

I've an integration almost exactly like yours. I can generate Unit and Integration tests coverage reports separately. They look okay. But when I look under jacocoTestReport directory, I see wrong generated xml and html file. Any idea why it can happen?

jacocoTestReport.xml:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><!DOCTYPE report PUBLIC "-//JACOCO//DTD Report 1.1//EN" "report.dtd"><report name="app"><sessioninfo id=".fritz.box-33d666fa" start="1681738688438" dump="1681738688994"/><sessioninfo id="unknownhost-e813c99c" start="1681738724566" dump="1681738746881"/><sessioninfo id="unknownhost-fe06a2d0" start="1681738749525" dump="1681738768653"/><sessioninfo id="unknownhost-ecc0ab0a" start="1681738771155" dump="1681738797417"/><sessioninfo id="unknownhost-1836ec94" start="1681738799956" dump="1681738836283"/></report>
