Request support for pre-processing "full" when using JDK >= 23

[jmborer]

As the pre-processing has changed since JDK 23 (https://inside.java/2024/06/18/quality-heads-up/) and is required by many NB platform functions, the NB Maven plugin shall force the compiler settings to:

<configuration>
      <proc>full</proc>
</configuration>

Or at least inform the user that it shall turn it to "full".

We should probably see if there's a way to provide a better warning. I don't think we should be changing the configuration, even if that's possible. @ebarboni what do you think on this one?

[ebarboni]

I don't think nbm plugin can alter configuration for compiler plugin. Maybe a hint in the IDE could help as well of having a condition in archetypes to add this line according to JDK version.

[neilcsmith-net]

Thanks! That's what I thought. Hint might be useful for pre-existing projects. Should move that request over to the IDE issue queue.

No need to add the archetype change according to version - should be OK to add in on all supported JDKs. There's a bunch of things that need updating in the archetypes already.

[jmborer]

Indeed, this is what I would expect as well. Conditional Maven profiles could be used as well to turn on the proper flag for the compiler. This could be generated by the archetype is a non-invasive way to provide proper flags to build NB based applications.

PS: I turned the proc to "full" on my projects with JDK23 and it works as before.

@jmborer feel free to submit a PR for either. No need for conditional profiles - this will work fine on all supported JDKs.
