Estoy usando Maven 3.0.3, JUnit 4.8.1 y Jacoco 0.6.3.201306030806, y estoy tratando de crear informes de cobertura de prueba.
Tengo un proyecto con pruebas unitarias solamente, pero no puedo ejecutar los informes, recibo repetidamente el error: Skipping JaCoCo execution due to missing execution data file
cuando ejecuto:
mvn clean install -P test-coverage
Así es como se configura mi pom:
<plugin>

Todas mis pruebas se ejecutan con éxito. Aquí está algunos de los resultados de Maven:

¿Alguna idea de qué configuración me falta?
destFile
y lo dejamos escribir en el archivo target / jacoco.exec predeterminado.
