NoSuchBeanDefinitionException: нет подходящего бина типа 'org.springframework.security.authentication.AuthenticationManager', доступного для gradle

Question

Я разрабатываю Rest API с Gradle, Spring Boot и Spring Security. API будет защищен с помощью токена аутентификации.

Однако, когда я запускаю приложение Spring Boot, я получаю следующую ошибку:

NoSuchBeanDefinitionException: нет подходящего компонента типа org.springframework.security.authentication.AuthenticationManager 'доступен

Вот WebSecurityConfig.java, где определен bean-компонент AuthenticationManager:

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)  
@Import({SkyscannerBeanConfiguration.class})
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired
private MyUserDetailsService myUserDetailsService;

@Bean
@Override
public AuthenticationManager authenticationManager() throws Exception{
    return super.authenticationManager();
}

@Bean
public BCryptPasswordEncoder passwordEncoder(){
    BCryptPasswordEncoder bCryptPasswordEncoder=new 
BCryptPasswordEncoder(11);
    return bCryptPasswordEncoder;
}

@Override
protected void configure(AuthenticationManagerBuilder auth) throws 
Exception{
}

@Override
protected void configure(HttpSecurity http) throws Exception{

        http
                .sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                .httpBasic()
                .realmName(securityRealm)
                .and()
                .csrf()
                .disable();
}

@Bean
public JwtAccessTokenConverter accessTokenConverter(){
    JwtAccessTokenConverter converter=new JwtAccessTokenConverter();
    converter.setSigningKey(signingKey);
    return converter;
}

@Bean
public TokenStore tokenStore(){
    return new JwtTokenStore(accessTokenConverter());
}

@Bean
@Primary
public DefaultTokenServices tokenServices(){
    DefaultTokenServices defaultTokenServices=new 
DefaultTokenServices();
    defaultTokenServices.setTokenStore(tokenStore());
    defaultTokenServices.setSupportRefreshToken(true);
    return defaultTokenServices;
 }
} 

А вот файл AuthorizationServerConfig.java, в котором bean-компонент AuthenticationManager подключен автоматически.

@Configuration
@EnableAuthorizationServer
@Import({WebSecurityConfig.class,SkyscannerBeanConfiguration.class})
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
private TokenStore tokenStore;

@Autowired
private JwtAccessTokenConverter 
accessTokenConverter;

@Autowired
private AuthenticationManager 
authenticationManager;

@Autowired
private PasswordEncoder passwordEncoder;

@Override
public void  
configure(ClientDetailsServiceConfigurer 
configurer) throws Exception{
    configurer
            .inMemory()
            .withClient(clientId)

.secret(passwordEncoder.encode(clientSecret))
            .authorizedGrantTypes(grantType)
            .scopes(scopeRead,scopeWrite)
            .resourceIds(resourceIds);
}

@Override
public void 
configure(AuthorizationServerEndpointsConfigurer 
endpoints) throws Exception{
    TokenEnhancerChain enhancerChain=new 
TokenEnhancerChain();


enhancerChain.setTokenEnhancers(Arrays.asList(accessTokenConverter));
        endpoints.tokenStore(tokenStore)
                .accessTokenConverter(accessTokenConverter)
                .tokenEnhancer(enhancerChain)
                .authenticationManager(authenticationManager);


 }
}

Вот файл приложения SpringBoot:

@ComponentScan("com.skyscanner.config")
@Import({WebConfig.class, SkyscannerBeanConfiguration.class,WebSecurityConfig.class, WebDatabaseConfig.class, AuthorizationServerConfig.class, AdditionalWebConfig.class})
@SpringBootApplication
public class DataServiceApplication {
    public static void main(String[] args){
        SpringApplication.run(DataServiceApplication.class,args);
    }
}

Вот файл build.gradle:

 buildscript {
    repositories {
        mavenCentral()
    }
    ext {
        springBootVersion = '2.1.3.RELEASE'
