Description

In the example script below, the use of the "owner" qualifier causes an error. Replace with "delegate" and no error. Disable static compilation and no error.

class C1 {
  void m() {
    print 'outer delegate'
  }
}
class C2 {
  void m() {
    print 'inner delegate'
  }
}
void outer(@DelegatesTo(value = C1) Closure block) {
  block.delegate = new C1()
  block()
}
void inner(@DelegatesTo(value = C2, strategy = Closure.DELEGATE_FIRST) Closure block) {
  block.delegate = new C2()
  block()
}

@groovy.transform.CompileStatic // comment out and script prints "outer delegate" as expected
void test() {
  outer {
    inner {
      owner.m() // "Cannot find matching method Script#m(). Please check if the declared type is right and if the method exists."
      // replace "owner" with "delegate" and CompileStatic has no error and prints "inner delegate" as expected
    }
  }
}

test()
