[keycloak-user] Uncaught server error: java.lang.NoClassDefFoundError: org/keycloak/services/validation/Validation

[Bo.Y at dell.com]

Hi Experts,

When I follow https://www.keycloak.org/docs/latest/server_development/index.html#packaging-the-action step by step to do customize the validation in keycloak. After I throw my jar into standalone/deployment, it creates a deployed file and the log shows the jar is deployed.  I can found my execution in keycloak admin console which shows in the screen shot below. But when it comes to register page, after I click register button with my filled content I got exception in keycloak log file. I also checked `standalone.xml` and `jboss-deployment-structure.xml` which seems fine too which means it include "keycloak-services-4.7.0.Final.jar". I don't find any useful information in the search. So could anyone help to have a look please?

Keycloak  version:
    compile group: 'org.keycloak', name: 'keycloak-core', version: '4.7.0.Final'
    compile group: 'org.keycloak', name: 'keycloak-server-spi', version: '4.7.0.Final'
    compile group: 'org.keycloak', name: 'keycloak-server-spi-private', version: '4.7.0.Final'
    compile group: 'org.keycloak', name: 'keycloak-services', version: '4.7.0.Final'
