Jacoco - Gradle - Can't add different class with same name - gradle

Question

I am trying to generate a coverage report for my integration tests using jacoco plugin and gradle but I am getting the following error.
java.lang.IllegalStateException: Can't add different class with same name: com/example/application/Application

From what I read in Jacoco FAQ this error is related to having two classes with the same name.
Is there any way to know which class is throwing this error? From reading the log it seems that it's not specified the troublesome class.
This is how my stage at my declarative pipeline ( Jenkinsfile) to generate the mentioned report
stage('Integration Test Coverage report') {
steps {
dir('') {
jacoco exclusionPattern: '**/*Test*.class,**/groovy/**', classPattern: '**/classes', sourcePattern: '**/src/main/java', execPattern: '**/integrationTest.exec'
}
}
}
How can I solve this problem?
Also, from reading Jenkins log I also found this information
