[keycloak-user] java.lang.NoClassDefFoundError in a customized Reset password authentication flow

[GESLIN Fabrice]

Hi,


We're trying to customize the reset password flow by providing a custom authenticator

ResetCredentialEmailSms to replace the ResetCredentialEmail provided by default in Keycloak


In our ResetCredentialEmailSms class, as in the original ResetCredentialEmail, we're importing and using the org.keycloak.authentication.actiontoken.resetcred.ResetCredentialsActionToken class .


We can build our authenticator successfully with no warning or error of any kind but at runtime we got the following issue :


^[[36mkeycloak    |^[[0m ^[[0m^[[31m12:06:43,542 ERROR [org.keycloak.services.error.KeycloakErrorHandler] (default task-1) Uncaught server error: java.lang.NoClassDefFoundError: org/keycloak/authentication/actiontoken/resetcred/ResetCredentialsActionToken

Any clue about what we did wrong ?
