make installing simpler

[eval]

Feedback from /r/clojure:

it'd be lovely to have a ready-to-use binary release instead of having to install bbin from a Homebrew (because that would be like third package manager I have on my Linux, which is two more than a reasonable amount).

[eval]

@lockie homebrew installation was just released: brew install eval/brew/deps-try.
Standalone released could improve installation further.

[lockie]

@eval thank you! Unfortunately trying to start deps-try.jar from the Releases section yields the following error:

$ java -jar deps-try.jar
Error: Could not find or load main class eval.deps_try
Caused by: java.lang.ClassNotFoundException: eval.deps_try

[eval]

@lockie it's an uberjar that can be run by babashka (I'll update the url to reflect that). Quick experiment to produce a java uberjar yields a jar over 800MB...

[lockie]

Oh, got it. Sorry, I'm still new to the Java world :sweat_smile: Trying to run deps-try uberjar with bb, I'm getting another error though:

[eval]

Was this after just running deps-try or deps-try some/lib?
Does clj -Sdeps '{:deps {metosin/malli {:mvn/version "RELEASE"}}}' start a repl? Does starting deps-try thereafter work?

[lockie]

Just a regular deps-try. The command you've provided indeed does start a repl after downloading a bunch of stuff. Running deps-try afterwards unfortunately produces the very same error (but the log starts with * run-java-tool was invoked directly now). Perhaps it has something to do with the weird way I have Clojure installed? I've done that with Guix package manager that runs on top of my distribution (which would be Gentoo GNU/Linux).

[eval]

I tried installing Guix on a Gentoo Docker instance but abandoned when issues regarding kernel settings came up... so the following is some guess-work:

You could verify that the following is indeed the minimal case (this gets deps-try out of the equation): bb -e '(babashka.deps/add-deps (quote {:deps {org.clojure/tools.gitlibs {:mvn/version "2.4.181"}}}))(prn :success)'

Then you might try checking the permissions of the cache-folder. Otherwise play around with env-settings CLJ_CACHE or XDG_CACHE_HOME: env CLJ_CACHE=~/tmp/clj-cache deps-try: env CLJ_CACHE=~/tmp/clj-cache bb -e '(babashka.deps/add-deps (quote {:deps {org.clojure/tools.gitlibs {:mvn/version "2.4.181"}}}))(prn :success)'.

[lockie]

Unfortunately all of the commands you've provided fail with the similar error message, only when I specify different CLJ_CACHE, they fail to find the mysterious file /tmp/clj-cache/1E81C60BC0AE3386072E94F5C403ECA7.cp, while the folder in question only contains the following files: 1151453926.basis, 1151453926.cp and 1151453926.libs. I feel like I might be hitting some bug in Clojure/Babashka infrastructure...

[eval]

😞 Maybe worth to bring this up in the babashka-channel of the Clojurians-Slack or Basbashka issue-list...

[lockie]

I'll do that. Thank you Gert!

[eval]

@lockie I shipped a new unstable version that might fix this (it also includes the latest Clojure alpha2): https://github.com/eval/deps-try/releases/tag/unstable (jar-file shrunk from ~13.5 to ~3MB).

[lockie]

@eval sorry to report it produces the same error message for me :weary:

[eval]

@lockie I just created a release that no longer depends on babashka.deps. I'm curious if this might (finally) fix this issue...

[lockie]

Thanks, it works for me now! Even though it says something about outdated Clojure CLI:

Adding (additional) libraries to this REPL-session via ':deps/try some/lib' won't work as it requires Clojure CLI version >= 1.11.1.1273 (current: 1.11.1.1165).

[eval]

Thanks for confirming it now works :).

Upgrading Clojure would solve the warning.
