I created a mapper plugin as described by: [Server Developer Guide](https://www.keycloak.org/docs/latest/server_development/#create-a-jar-with-the-scripts-to-deploy)

Loaded the jar via:  
kind: Keycloak  
extensions:  
- [http://xxx/yyy/myplugin.jar](http://xxx/yyy/myplugin.jar)

I see a string saying its loading the module on the console.

But it doesn’t show up in the list of available mappers. Is there some other flag I need? if so, how do I specify it in the Keycloak object?

I managed to get it to work. it wouldn’t load when I added:

```auto
  keycloakDeploymentSpec:
    experimental:
      command:
      - /opt/jboss/tools/docker-entrypoint.sh
      args:
      - -b0.0.0.0
      - -Dkeycloak.profile.feature.scripts=enabled 

But did show up when I added an additional line:
      - -Dkeycloak.profile.feature.upload_scripts=enabled 

Feels like somethings broken in 15.0.2 that upload_scripts must be enabled to get script jars to work.
```

And to load it, in the KeycloakClient:
