title: Grails 4 Spring Security Plugin
body: <p>After upgrading from Grails 3.3.9 to 4 there are several packages missing. E.g. <code>unable to resolve class org.springframework.security.provisioning.JdbcUserDetailsManager</code>. Has anyone any ideas? I've done all the steps from here: <a href="https://docs.grails.org/4.0.0.M1/guide/upgrading.html" rel="nofollow noreferrer">https://docs.grails.org/4.0.0.M1/guide/upgrading.html</a>.
  It seems that Gradle 5 can not load all the dependencies in the plugin. With Grails 3.3.9 and Gradle Wrapper 3.5 everything worked fine.
  Thanks for any advices.</p>
