[periklis]

@teozkr thx for the guidance and since i am on that path i decided to push this forward later this week.
Current state of affairs #34 :

to be continued

@teozkr I had some time today to fix the build. The current version just compiles and has zero deprecation warnings, nothing more. I am actually stuck with a local error with the ensime global plugin, hence i could not proceed with sbt genNix "reload plugins" genNix.

[nightkr]

Yeah, you should probably disable Ensime while running genNix by hand. Normally sbtix-gen-* is set up to ignore global plugins, but that becomes a bit circular when there isn't a packaged Sbtix for that version yet.

[periklis]

Actually coursier changed (See CachedPath) a little bit and it caches paths and locks in files with a dot prepended, which breaks with nix, because its an names with dots are illegal.
