following instructions results in not being able to find the rebl class

[drewverlee]

Calling C-x C-r results in

Execution error (ClassNotFoundException) at java.net.URLClassLoader/findClass (URLClassLoader.java:445). cognitect.rebl.

If i don't follow the library instructions, and use these main-opts :main-opts ["-m" "cognitect.rebl"] from the datomic page, then call clj -A:rebl, it will start

rebel is in my dir locals as you can see from the cider startup info dump

Updating the following line in my :rebl alias fixed the issue for me:

com.cognitect/rebl          {:mvn/version "0.9.245"} 

The version number has to match the version of REBL that you downloaded from Cognitect dev-tools.
