while it works fine with 3.0.0-M2-15-9bed9700

This is expected because upickle does not support scala 3.3.3 due to a compiler macro issue IIRC, so both only support 3.4.2 and above

[Gedochao]

Right. So we should downgrade to 3.0.0-M2-15-9bed9700 for Scala <3.4.2. 😞 Got it.

Once Scala 3.3.4 or 3.3.5 comes out we can add back support in Ammonite 3.x, see this pr for details com-lihaoyi/upickle#610

[Gedochao]

Yeah... it's slightly awkward where I'd have to do special handling for <3.4.2 for the time being... or just not upgrade ammonite in Scala CLI until the fix is in place.
Leaning towards the latter.

Also, iI find it a bit odd for this to be introduced in Ammonite 3.0.0 (the first stable release since 2.5.11). This is essentially removing Scala LTS support, even if it's temporary... 😕

[lihaoyi]

I'd say just don't upgrade if it's inconvenient. If I didn't publish Ammonite 3.0.0, that's what you would be doing anyway. Ammonite 3.0.0 has been overdue for years now, so I wanted it out sooner rather than later, and I didn't want to hold back everyone on 2.12/2.13/3.4/3.5 just because some bugs in 3.3.3 haven't been fixed yet

BTW Scala 3.3.4 artifacts are up, not sure if that doesn't help already.
