Idle thought - when is someone going to use the babashka tasks API to implement a build tool and package manager?

hugod22:11:11

I’m working on makejack which provides build tasks that mostly are capable of running with bb. It includes a standalone bb script , which you can download and run https://github.com/hugoduncan/makejack/blob/main/mj Still alpha at the moment, but I’m using it one other project. The project is here https://github.com/hugoduncan/makejack

hugod22:11:37

@U04V15CAJ has updated bb, and together with a tools-deps-native pod, we can run tools.build tasks.

This is my babashka build config.

Works amazing!

I'm having problem with bb finding 'clojure.main' I installed clojure using brew, and it's located in '/opt/homebrew/bin/clojure'. But when I attempt to run a clojure program using bb (i.e., bb -m foo.main) I get the error 'Could not find or load main class clojure.main' I have clojure as a dependency in my bb.edn file. Thanks in advance for any help in solving this one.

borkdude21:11:54

Hi! You don't need clojure as a dependency for babahska. Babashka is a standalone binary. This error message seems to be coming from a JVM, perhaps because babashka is trying to download dependencies for which it uses clojure.

borkdude21:11:15

Can you try just clojure --version and see what it prints?

borkdude21:11:36

Note that you have to use the clojure tap, not the package from homebrew itself: https://clojure.org/guides/getting_started#_installation_on_mac_via_homebrew

adkelley21:11:46

Thanks. It's shows me the help docs. Note I also installed java using brew. opt/homebrew/opt/openjdk/bin

borkdude21:11:23

--version please

adkelley21:11:40

1.10.3.1029

borkdude21:11:55

ok, that looks normal. I'll be right back.

adkelley21:11:59

I didn't use the clojure tap though for homebrew. I used the core tap. Let me reinstall

adkelley21:11:50

No difference

borkdude22:11:50

ok, I'm back now

borkdude22:11:10

can you test this? clojure -M -e '(+ 1 2 3)'?

adkelley22:11:22

That works fine

adkelley22:11:28

I'm attempting the example from your Project Setup section in the Babashka book. bb -m my-project.main Error: Could not find or load main class clojure.main Caused by: java.lang.ClassNotFoundException: clojure.main

adkelley22:11:22

. ├── bb.edn └── script   └── my_project     └── main.clj 2 directories, 2 files

borkdude22:11:38

what is in your bb.edn here?

borkdude22:11:09

and which version of bb do you have? bb --version

adkelley22:11:04

Interesting! That comes back Error: Could not find or load main class clojure.main Caused by: java.lang.ClassNotFoundException: clojure.main. Yet, I'm able to run bb scripts

adkelley22:11:36

I installed bb using homebrew - /opt/homebrew/bin/bb

borkdude22:11:52

which version?

adkelley22:11:55

Ahh... When I get out of the project directory. bb --version works fine. V0.6.5

borkdude22:11:20

there might be an error in your bb.edn. I tried the sample project from the book and it worked fine here

borkdude22:11:43

if you can put up this repro in a github repo I can try it locally

adkelley22:11:50

{:paths ["script"]  :deps {medley/medley {:mvn/version "1.3.0"}}}

borkdude22:11:24

can you go out of this directory and try: bb clojure --version

adkelley22:11:50

I got an exception

adkelley22:11:05

Exception in thread "main" java.io.FileNotFoundException: /Users/alexkelley/.clojure/.cpcache/363A78F07197DB7FD0EDF27138B9FAFF.cp (No such file or directory)

borkdude22:11:31

can you try: rm -rf ~/.deps.clj

borkdude22:11:37

and then try again?

borkdude22:11:08

don't worry, .deps.clj is created by bb, you can safely remove it

Yes. /Users/alexkelley/.clojure ├── deps.edn └── tools   └── tools.edn 1 directory, 2 files

borkdude22:11:01

Does the directory /Users/alexkelley/.clojure/.cpcache exist?

borkdude22:11:59

and no file:

/Users/alexkelley/.clojure/.cpcache/363A78F07197DB7FD0EDF27138B9FAFF.cp
or so?

borkdude22:11:14

what do you get for java --version?

Are you able to run JVM Clojure projects with dependencies using clojure?

borkdude22:11:04

Try this:

$ cp bb.edn deps.edn
$ clojure -M -m my-project.main

adkelley22:11:45

Interesting. Now the bb version works?

can you try to remove this .cpcache dir and then try again with bb only?

Please write up an issue with details from this discussion if you have the time... I'll take a look at reproducing the issue locally. I'm not sure what it is right now

adkelley22:11:47

Now my projects are working again! Yay!

borkdude22:11:57

Perhaps the clojure bash script copied some file that the bb one didn't do or so.

borkdude22:11:02

Which made it work

adkelley22:11:44

I will. This is very strange. Clearly that was the trigger.

adkelley22:11:10

Thank you so much! I've been trying to get back on track after upgrading to an M1 last week.
