Description

import groovy.transform.CompileStatic

interface Bar {
  String getField()
}

class BarImpl implements Bar {
  String field
}

class Foo {
  Bar bar

  Foo(String field) {
    this.bar = new BarImpl(field: field)
  }
}

@CompileStatic
class Tester {
  void test() {
    Foo foo = new Foo('value')
    println foo.bar.with { "$field" }
  }
}

new Tester().test()

when compiled with groovyc results in the following compilation error:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
bad.groovy: 23: [Static type checking] - The variable [field] is undeclared.
 @ line 23, column 28.
   		println foo.bar.with { "$field" }
                              ^

1 error

However, without the @CompileStatic on the Tester class, the code compiles cleanly and runs successfully.

From what I've been able to discern, the compilation error does not occur if the with() occurs on the 'top-level' object and only occurs when the contained/subordinate object is an interface.
