Would you be interested in a PR with a ksp-maven-plugin which you would take over as an official maven plugin?
We currently have (at least) two inofficial ksp-maven-plugins (
https://github.com/mcarleio/ksp-maven-plugin and
https://github.com/kpavlov/ksp-maven-plugin) but still lack an official one. I think it would be valueable for KSP. And the amount of extra code to maintain is also not very high.
If you are interested, I would try to join forces with
@Konstantin and create a PR.
