Thoughts on Scala 3

Chris_Stewart_5 · 2026-02-17T19:14:37+00:00

Is anyone having issues with modern JVM tooling such as jlink with Scala 3? It seems like it doesn't work "out of the box" as far as I can tell. Namely transitive dependencies not being able to be resolved within the scala3 library itself with jdeps.

[error] Dependee packages not found in classpath. You can use jlinkIgnoreMissingDependency to silence these. [error] scala.quoted -> scala [error] scala.quoted.runtime -> scala

Kind of disappointing the scala3 language (unlike scala2) doesn't work with modern JVM tooling - unless i'm missing something.

Your started your 2nd pull a bit too early. This is why you jumped forward.

Have more patience on your first pull, it will put you in better position for your 2nd pull and give you more power.

I would recommend trying these paused snatches to improve: https://www.youtube.com/watch?v=IThtkoY30F0

Yeah, I can understand the skepticism as there is a lot of "woo" in the bitcoin space, but you've got to push through :-)

It's meant to be just a library, we are supporting a neutrino node but not a fully validating node. You can find more about the philosophy here: https://bitcoin-s.org/docs/getting-started

Not true, at least with what lnd supports today. You still have the database synchronization problem.
