LGTM, I verified it, and it did create the credentials.properties correctly. I'm not sure if the content is 💯 accurate as I am not familiar with this part of the code.

[dimakis]

I would just call it java-properties

[rkpattnaik780]

That did occur to me. But since .properties file are primarily used for java-related technologies, this name sounded redundant.

This is java-kafka specific, so the name you've chosen seems reasonable.

Thanks for the verifying.
