GRAILS Dynamic methods missing after enabling plugin

[roanosullivan]

For example, during login attempt (using spring-security plugin), I get:

Error 500: Internal Server Error
URI
/j_spring_security_check
Class
groovy.lang.MissingMethodException
Message
No signature of method: static com.example.MyUser.findByUsername() is applicable for argument types: (java.lang.String) values: [admin]

When I disable the plugin (and remove @LogicalDelete annotation from domain class) , login succeeds, so presumably MyUser dynamic methods are no longer missing.

Environment:

• Grails 2.3.6,
• JDK 1.7.0_51,
• Windows 7,
• BuildConfig.groovy:
  • runtime ":hibernate:3.6.10.12"
  • compile ":hibernate-filter:0.3.2"
  • compile ":envers:2.1.0"
  • etc.
