Пустой отчет плагин jacoco и Jenkins

У меня есть проект, где я использую Jacoco для вычисления покрытия кода. Я использую конфигурацию maven, как здесь:

http://www.petrikainulainen.net/programming/maven/creating-code-coverage-reports-for-unit-and-integration-tests-with-the-jacoco-maven-plugin/

С Дженкинсом я запускаю "mvn clean install test". Он генерирует отчет в папке/target/site/ jacoco-ut/. Если я открою указатель.HTML-файл, я вижу это :

но когда я открываю отчет покрытия JaCoCo в задании Дженкинса, я вижу это:

Он говорит, что каждый тест покрывает 0% кода. Я не понимаю, почему у меня нет того же результата, что и в html-отчете.
