[keycloak-user] Keycloak development setup

Hi, I need to adapt Keycloak and tried to set up a development project in IntelliJ but I couldn't figure out how to do it so that hot code replacement and other IDE integrations work. I used to hack on Keycloak but back then it was possible to create a simple WAR overlay and deploy that to the local server - easy. But with the newest version, only the Keycloak Wildfly subsystem distribution seems to be supported and I wonder how a development setup would look like given this restriction? Could not find any pointers on this, unfortunately. Thanks! Moritz
