Sonarqube reliability lint in examples - I have renamed the sonarqube config file on the batch branch so that we exclude examples from the copy-paste analysis. You might like to do the same here to get past the quality gate. The previous config file name was incorrect for the analysis mode we are using and had no effect.

The sonarqube config is now in main

Not in your PR, but can you change the example CLI interaction in examples/README.md to use a different example, as core now has the nested projects?

# Switch to the directory containing an example for the powertools-core module
$ cd powertools-examples-core

powertools-examples-idempotency might be a good one!

Looking great! I've gone through all the markdown and code again and tested both the deploys. One more point in addition to the comment above (README link), and then we're good to go.

All the java files in examples/powertools-core need 1/ the function headers (e.g. and license-header file) and 2/ to be run through checkstyle (see here).

I believe we started doing this since you've taken your branch.

Once you've got these two we can merge 💪 Thanks for the persistence!
