I'm wanting to test out this extension for a proof-of-concept, but am running in to an error when trying to install it with the quick installation steps. Please let me know if you think I'm missing anything in the steps I'm following

Expected Behavior

I would expect the steps I'm following to install keycloak-scim and make the functionality available in a local dev environment of Keycloak.

Current Behavior

Instead I am seeing the following error (note this is the end of it but the full output is very long):

Steps to Reproduce

  1. Run keycloak: docker run -p 8080:8080 -e KEYCLOAK_ADMIN=admin -e KEYCLOAK_ADMIN_PASSWORD=admin quay.io/keycloak/keycloak:25.0.1 start-dev
  2. Use docker ps to get ID of container - eg: 50e04c077e09
  3. Download latest version: keycloak-scim-1.0-SNAPSHOT-all.jar
  4. Copy in to running container: docker cp ~/Downloads/keycloak-scim-1.0-SNAPSHOT-all.jar 50e04c077e09:/opt/keycloak/providers/.
  5. Open container shell: docker exec -it 50e04c077e09 bash
  6. Re-build: /opt/keycloak/bin/kc.sh build

I ran the steps you mentioned trying to reproduce the error, however I was unable to. I initially thought it might be a breaking change in the new version of Keycloak so I tested out 24.0.0 and that worked fine. I then tested 25.0.1 and I still didn't run into issues when following the steps referenced.

Thanks for checking it out @shaidar - I'll experiment a bit more to see if I can figure out why it's not working and report back if I can find a solution. Let me know if you have any ideas for things I can try that may be different on my system compared to yours.

I can run /opt/keycloak/bin/kc.sh build fine if I move keycloak-scim-1.0-SNAPSHOT-all.jar out of the /opt/keycloak/providers/ directory and then running /opt/keycloak/bin/kc.sh show-config gives me (note I tested it with Keycloak 24.0.2 this time):

I ran into the same problem. You have to download the fatjar from the Github Releases page (15MB). The JAR from the README link doesn't contain all the dependencies (1.4MB).

Great, thanks @fhussonnois ! I've gone with another solution for now, but will probably revisit this in the future
