1 year ago Thanks. I can confirm that it works well on maven 3.9.5. Maven 3.6.3 is the distribution included version in both Ubuntu 20 and 22 so I'm making a small pull-request for the README.md
Running "mvn verify" is part of the setup-script and it creates paths and files needed later. Trying to run it using openjdk-1.17 causes an error as below:

Changing to Java 11 avoids the error (will give warning instead)
