[keycloak-user] SysoutEventListenerProvider example is not working

[Sarp Kaya]

Hello,

I have followed the instructions in the provided example (from keycloak-examples-1.9.4.Final.zip). The steps I have done are:


  1.  ran mvn clean install
  2.  Copied event-listener-sysout-example.jar file from target to providers directory in keycloak
  3.  Registered provider in keycloak-server.json
  4.  Restarted the standalone server

I am getting the error below now:

Am I missing an unknown step? The readme file only mentions copying the jar file to providers. If not what could be wrong?

Kind Regards,
