REPL does not automatically select .shadow-cljs/nrepl.port for nREPL connection type

[jdhollis]

Hi, Colin.

Ran into an issue with “Use standard port file” with an “nREPL” connection type to shadow-cljs. It seems that .shadow-cljs/socket-repl.port is being picked up instead, resulting in the following exception:

Exception starting REPL: java.lang.IllegalStateException: Could not open new session; :clone response: Disconnected from remote server.

If I explicitly specify .shadow-cljs/nrepl.port, everything works as expected.

For reference, I’m using IntelliJ 2022.3.1 (Build #IU-223.8214.52) with Cursive 1.12.7-eap1-2022.3.

I actually do have the same issue after upgrading to Cursive 1.12.7 2022.3 - IntelliJ IDEA 2022.3.2 (CE).
My nREPL is started by an external process and puts a file .nrepl-port at project source root.

My setting: Edit Configurations > Remote REPL > Use port from REPL file > Use standard port file no longer works and produces:

Connecting to remote nREPL server...
Exception starting REPL: java.lang.IllegalStateException: Could not open new session; :clone response: Disconnected from remote server.

Our nREPL is not started by shadow, and it produces a regular .nrepl-port file. In fact, by setting the option Specify custom port file to .nrepl-port it does connect fine as mentioned by @jdhollis.
