`CompilerException java.lang.RuntimeException: No such var: encore/kw-identical?, compiling:(taoensso/carmine/protocol.clj:256:3)`

Hullo --

I'm not terribly sure what's gone awry, but I'm running in to problems using carmine 2.8.0 at the repl or within Emacs. The project lein compiles just fine, but then I hit this:

$ lein repl
nREPL server started on port 53725 on host 127.0.0.1 - nrepl://127.0.0.1:53725

CompilerException java.lang.RuntimeException: No such var: encore/kw-identical?, compiling:(taoensso/carmine/protocol.clj:256:3)

Thoughts? Suggestions?

For what it's worth, the problem vanishes when I drop back down to carmine 2.7.1.

Hi Ross,

Looks like you're experiencing a dependency conflict (which you could confirm by running lein deps :tree at your command line).

Easy fix is to include the latest version of Encore (currently [com.taoensso/encore "1.16.2"]) in your project.clj above any other taoensso libs (so that it'll override any older imports).

Does that help?

[Gastove]

Yep -- looks like it was conflicting with the version of encore brought in by [com.taoensso/timbre "3.2.1"] Explicitly declaring the dep fixed it -- and I've learned about lein deps :tree, which I didn't previously know about. So! Thank you on both counts.

I don't know if this is an "issue" you'll want to "fix", so I'll leave closing this up to you?

[ptaoussanis]

No problem, thanks for following up! Just shout if you run into any other issues. Cheers :-)

2.7.1 and removing the project's target directory worked for me

[ptaoussanis]

@mgamba - no need to drop to 2.7.1, you can just include an explicit encore dependency in your project.clj as discussed above. That'll sort out any possible dependency conflict. Cheers! :-)

[mgamba]

[com.taoensso/encore "1.16.2"]
[com.taoensso/carmine "2.9.0"]
[com.taoensso/timbre "3.2.1"]

works. thanks!

you should delete target dir and restart again!
