@katox merged, thanks

now for your babashka compilation problem: have you solved this too?

no, let's move to a proper forum .)

we can do in private.

for the record, the error was cloning the repo without --recursive, thanks!

I think all the ingredients for an all native deps.edn / tools.deps CLI are there now: https://github.com/borkdude/tools-deps-native-experiment/tree/shell#shell-branch This + deps.clj = no JVM for dep resolution / downloading, just JVM for REPL / running of apps / bytecode AOT compilation

Will wait a bit for the shell approach to appear properly in tools.deps.alpha.

What do we win with this? Maybe a bit questionable to go through these hoops, but: - startup time for downloading deps - running this is about as fast with caching of the CLI as it is without, if the deps are already there - could be used in babashka to decouple downloading of scripting deps from a JVM

what percentage of execution time is startup vs. downloading deps?

it depends on how many deps you have

and how fast your network is

and how much is in your cache :)

I will do a small test locally with only medley

300ms vs 3000ms

(with medley and .cpcache removed from local caches)

The comparison wasn't entirely fair because I ran clojure in my tools-deps-native project which had more deps so calculating the classpath would take more time. Better comparison:

Update regarding tools-deps-native. The GraalVM problems have now vanished due to getting rid of Jsch.

The startup time + downloading medley with clojure at 1.10.2.801 (which doesn't use JSch anymore) also seems to have improved a little, now down to 2s compared to 2.5s above
