Hi boot-clj team,

Recently I've started to come across the following error on global boot repl

Abhinavs-MacBook-Pro:~ eklavya$ boot repl

Please let me know how to resolve this.

Hey @abhi18av :wave: This looks like a configuration issue. Could you share your configuration files as described in the issue template? Thanks!

Whoops, let me correct my mistake here.

@abhi18av Do you have a local build.boot file? And can you also provide the output of boot -V? Thanks

abhi18av commented 5 years ago

@martinklepsch , no I'm just trying to have a bare minimal repl for clojure ( apart from clj etc ) so no, I don't have any build.boot in the directory.

Also, here's the output you requested

Can you try with version 2.7.2 just to diagnose if the issue might be related to your particular version? If you use Bash or similar:

BOOT_VERSION=2.7.2 boot repl
abhi18av commented 5 years ago

@martinklepsch , we're on right track here.

The behavior is perfectly normal for this version.

@abhi18av The warning is harmless. It comes from a broken version of REPL-y - adding the most recent version somewhere in your project will suppress it, but everything will work perfectly fine in spite of it. I guess I should fire away some PR bumping the version of REPL-y and nREPL bundled with boot.

bbatsov commented 5 years ago

See https://github.com/trptcolin/reply/pull/192/files for details.

thedavidmeister commented 5 years ago

dropping from boot 2.8.2 to 2.7.2 with latest deps of everything else according to boot show -u fixed this for me

bbatsov commented 5 years ago

There's an open PR to update the bundled REPL-y https://github.com/boot-clj/boot/pull/724

The downgrade you suggest will break clients that depend on a recent nREPL version, so I think it's a bad idea, considering the error is relatively harmless. I'm guessing the overriding the REPL-y version locally should work ok as well.

burn2delete commented 5 years ago

closing as v2.8.3 is out with updated deps
