Issue: Close JUnit and hamcrest
and #328

[iluwatar]

• Add the new module (ETL) to parent pom.xml. Otherwise it won't be built by CI.
• ETL module is missing README.md. See contribution instructions to grasp the format that is required.
• Actually, the other issue you are referencing (Update to JUnit 5 uml-reverse-mapper#91) belongs to uml-reverse-mapper project. But probably it is applicable here as well 🙂
