J'utilise Maven 3.0.3, JUnit 4.8.1 et Jacoco 0.6.3.201306030806, et j'essaie de créer des rapports de couverture de test.
J'ai un projet avec uniquement des tests unitaires, mais je n'arrive pas à faire fonctionner les rapports, j'obtiens sans cesse l'erreur suivante : Skipping JaCoCo execution due to missing execution data file
quand je cours :
mvn clean install -P test-coverage
Voici comment mon pom est configuré :

Tous mes tests se déroulent avec succès. Voici une partie de la sortie de Maven :

Une idée de la configuration qui me manque ?
