I have an existing project (non-DX) in which I've lost the ability to associate a SF org connection. It used to work, but the IDE hung this morning trying to open my project, the dialog shown was "listing Salesforce DX connections". I had to force-kill Intellij. Tried multiple times to restart to no avail. After getting around that by having Intellij not reopen the project by default, I opened the project manually and the connection was no longer associated. I tried to set it via the "modules and connections" dialog (from Illuminated Cloud -> Configure Project context menu), but the list of available connections is blank.
I've tried: - Removing all connections except the one I'm using - Removing all connections totally and adding the one I'm using from scratch - Removing / reinstalling IC plugin / adding back the connection - Deleting my project entire, cloning fresh from git, creating IntelliJ project from scratch.
None of these allow me to see the connection and associate it with my project. The bizarre thing is that this was working fine until the hang this morning. I see nothing else to point to as the possible cause.
But I'm basically dead in the water - I have to go find another development tool as I can't get this working.
