Jacoco report aggregate shows 0 coverage even if tests were executed

Question

My maven project directory structure is as follows:

parent
  -child
    -src/java
    -src/test <!-- unit tests -->
    -pom.xml
  -integration_test
    -src/test
    -pom.xml
  -report
    -pom.xml
  -pom.xml

Since integration tests and source code are in different modules I used Jacoco report-aggragate (report module).

Parent pom.xml

The unit tests code coverage report is displayed correctly, but for integration tests even though the tests are executed, the code coverage is given as 0
