incremental compilation of Scala 3

In this post, I want to look into the incremental compilation of Scala 3, or the apparent problem associated with it. The incremental compilation on Scala 2.12 or 2.13 has been fairly stable, but for some reason it&rsquo;s more fragile on Scala 3.x in my experience. We will investigate the cause and attempt to fix it as scala/scala3#24171 .
