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’s more fragile on Scala 3.x in my experience. We will investigate the cause and attempt to fix it as scala/scala3#24171.

allowUnsafeScalaLibUpgrade settingThis is a blog post on sbt 2.x development, continuing from sbt 2.x remote cache, sudori part 4, part 5 etc. I work on sbt 2.x in my own time with collaboration with the Scala Center and other volunteers, like Billy at EngFlow. Lately I’ve been working on a feature called client-side run, a feature I’ve thought sbt should have for a long time.
A client-side run is an execution of the user-land program initiated at the client-side, without blocking the sbt server. I should probably unpack the details for this to make sense.
Jar Jar Abrams 1.14.1 and sbt-assembly 2.3.1 are released.

I’m going to try to work on something small everyday during december. see the original December Adventure.
my goal: work on sbt 2.x, other open source like sbt 1.x and plugins, or some post on this site, like music or recipe.
checking out Boston suburbs. had coffee at Tatte Bakery & Cafe, and skated a bit at Newton Centre Playground nearby.

addressed a review comment on io#397, which retries non-IOExceptions.
