The QuarkusBootstrapProvider caches the AppArtifact causing problems

[gnodet]

The QuarkusBoostrapProvider has a cache of QuarkusAppBootstrapProvider which itself has a field for the AppArtifact.
This field is initialised with the initAppArtifact if not yet initialized.
However, this method creates the output build directory if it does not exists.

The causes problems if the cache is actually reused in a subsequent built after cleaning the project and leads to problems because the output directory has not been created.

So it breaks mvnd. mvn should work, right?

Yes, that's correct.
