Hello,
Maybe you have already solved your issue. I was also frustrated trying to make version 5.6.15.Final work. Here’s the key information that helped me:
https://github.com/stadler/hibernate-tools-maven-plugin-sample/blob/master/pom.xml
It is quite old, but I used it as a model, and it worked! Here is part of my pom.xml:
It’s similar to what you have, but you might be facing issues because your dependencies are defined later in the pom.xml.
In my case, my problem was that ChatGPT suggested putting the configuration inside the execution block, moreover before it was suggesting tags and configuration of 2.x plugin's version.
I hope this helps!
Regards.
