Getting a Java exception when I try to start CIDER:

@rjray > Caused by: java.lang.RuntimeException: Invalid token: ::clojure.test/once-fixtures Could it be that the given keyword is invalid?

That was a bug that was fixed in August of 2017. What version are you running?

https://github.com/clojure-emacs/cider/issues/2081

Good call... turns out my CIDER is out of date, because emacs' package manager can't update a needed dependency in order to update CIDER.

Do you know which one?

And probably best to just delete the dir from the elpa directory and reinstall

That's the problem-- this emacs seems to think it can't validate the GPG key for elpa, so no elpa packages were showing up after package-list-packages.

I cheated: I downloaded queue.el 0.2 directly from elpa and installed it via package-install-file. Updated cider, and now I'm working.

Ah. Update your emacs or google how to update the key. They had to update the keys and unfortunately the older emacsen were left in the lurch

Has it been a while since you’ve done clojure development?

So, cljr-find-usages is b0rken on our main project at work. I’d like to take a stab at debugging/fixing this, but I’m unfamiliar with how to effectively debug/change nrepl middleware. Anyone has any good resources on that?

Things I’d like to achieve: 1) call the middleware directly from the REPL. 2) change said middleware without restarting the REPL.

@rjray i had the same problem last month. i just package-install this package to force emacs to renew his GPG key, the package name is: gnu-elpa-keyring-update
