title: unable to execute s2ui-override layout
body: <p>Using Grails 3.1.9, spring-security-core 3.1.1 and spring-security-ui3.0.M2 I get the following when executing
  grails s2ui-override layout
  Command [s2ui-override] error: class path resource [layouts/springSecurityUI.gsp] cannot be opened because it does not exist (Use --stacktrace to see the full trace) 
  Any dieas on how to fix this or if spring-security-ui is even worth using? I noticed the only releases appear to have been milestone releases.</p>
