@GrailsCompileStatic in a command object breaks importFrom method call

[Macoshark]

Steps to Reproduce

1. Define a base command object that other command objects extend.

   @Validateable
   @GrailsCompileStatic
   class ApiCommandBase {
   String param
   ...

   static constraints = {
       param nullable: true
       ...
   }
   

   }

2. The extended command object imports the constraints from ApiCommandBase by calling the importFrom method.

   @Validateable
   @GrailsCompileStatic
   class AccountCmd extends ApiCommandBase {
   String username

   static constraints = {
       importFrom ApiCommandBase
       username blank: false
   }
   

   }

Expected Behaviour

The code compiles normally.

Actual Behaviour

This results in the following compilation error:

Compilation error: startup failed:
AccountCmd.groovy: 15: [Static type checking] - Cannot find matching method AccountCmd#importFrom(java.lang.Class <ApiCommandBase>). Please check if the declared type is right and if the method exists.
@ line 15, column 9.
           importFrom ApiCommandBase
           ^
1 error

Not sure it supports the constraints block yet. @jeffbrown ?

I had this issue a couple of days ago, forgot to open the ticket. From the docs http://docs.grails.org/latest/guide/staticTypeCheckingAndCompilation.html

Code that is marked with GrailsCompileStatic will all be statically compiled except for Grails specific interactions that cannot be statically compiled but that GrailsCompileStatic can identify as permissible for dynamic dispatch. These include things like invoking dynamic finders and DSL code in configuration blocks like constraints and mapping closures in domain classes.

it mentions constraints.

@graemerocher Yes, constraints is supported. The issue is that the type checking extension is being too strict in that it only allows calls to methods who's name matches the name of a field in the class. Will be a simple fix. https://github.com/grails/grails-core/blob/246b7264e8a638ada188ddba7a7a8812ba153399/grails-core/src/main/groovy/org/grails/compiler/ValidateableTypeCheckingExtension.groovy#L60
