Jacoco 代码覆盖率报告未为集成测试生成，未在声纳中显示

Question

I had configured Jacoco + Sonar in Maven. I am able to generate the coverage reports for unit tests & display the coverage in Sonar as well. But, unable to generate the reports for integration tests. "jacoco-it.exec" is generated but, when I go and open the index.html, it looks empty. But, there are many integration tests got executed & passed as well. In jacoco-sessions.html, it is clearly mentioned about all the classes which are used internally. Please help me if you have any idea what is wrong in the below code wrt integration tests. I have configured Sonar also properly & given the path to pick up the results for integrations tests. Please see once and help me if you have any idea. pom.xml:
