Clean artifact on build command

[tupui]

What problem does your feature solve?

Rumor has it (@kalepail) that building a contract sometimes fails if you don't first clean your targets.

What would you like to see?

Could the build command take care of that for us?

What alternatives are there?

Nothing, keep doing it as usual or maybe there is an underlying fundamental issue to solve or understand.

It would be great if there was a reproducible example. Is this in a multi crate workspace? What is the error?
