Class 'AuthenticationProviderUserPassword' does not implement abstract member public abstract fun authenticate - authentication

Question

I am stuck in user authentication with micronaut application
authenticate function not accepting httpRequest param
I'm getting an error
Class 'AuthenticationProviderUserPassword' is not abstract and does not implement abstract member public abstract fun authenticate(authenticationRequest: AuthenticationRequest<(raw) Any!, (raw) Any!>!): Publisher! defined in io.micronaut.security.authentication.Authenticatio
Service:
package example.micronaut.services
import io.micronaut.http.HttpRequest

import io.micronaut.security.authentication.AuthenticationProvider
import io.micronaut.security.authentication.AuthenticationRequest

import javax.inject.Singleton
#Singleton // <1>

override fun authenticate(httpRequest: HttpRequest<*>?, authenticationRequest: AuthenticationRequest<*, *>?): Publisher<AuthenticationResponse> {
if (authenticationRequest != null && authenticationRequest.identity != null && authenticationRequest.secret != null) {
if (authenticationRequest.identity == "sherlock" && authenticationRequest.secret == "password") {
return Flowable.just<AuthenticationResponse>(UserDetails(authenticationRequest.identity as String, ArrayList()))
}
}
return Flowable.just<AuthenticationResponse>(AuthenticationFailed())
}

The docs you are looking at are compatible with more recent versions of the interface than you are using. You appear to be using the one at https://github.com/micronaut-projects/micronaut-security/blob/78169cb6927d10dcc6ebc2f6ecb96efb26b9585b/security/src/main/java/io/micronaut/security/authentication/AuthenticationProvider.java#L39 which is why your code won't compile. 2.0RC1 looks like https://github.com/micronaut-projects/micronaut-security/blob/d5ecfc200cf27bd92ec7ce7b3760f5c264ec2647/security/src/main/java/io/micronaut/security/authentication/AuthenticationProvider.java#L44.
