Jochen Theodorou commented on GROOVY-9472:
------------------------------------------
[~paulk] I never used the annotation because frankly I have no use for it. But
if it is that "complicated" to use then (playing a new user's side here) I
would expect its limitations been documented. That some things don't work with
joint compilation is a big problem, but this does not work if it is in the same
compilation Unit and it is not even specific to @CompileStatic. As soon as you
reference the class in the same CompilationUnit in normal source code you get
a problem. For me this points to that the resolution of classes should not be a
single pass process if new sources are picked up during resolution, at least
not if we want to resolve an inner class of that. Of course I am aware of this
being complicated and introducing complications.

> Key: GROOVY-9472
> URL: https://issues.apache.org/jira/browse/GROOVY-9472
> Project: Groovy
> Issue Type: Bug
> Components: Compiler, Static Type Checker
> Affects Versions: 2.5.10
> Reporter: Daniil Ovchinnikov
> Assignee: Eric Milles
> Priority: Major
> Fix For: 4.0.0
>
>
> {code:groovy|title=com/foo/Person.groovy}
> package com.foo
> @groovy.transform.builder.Builder
> class Person {
> String name
> }
> {code}
> 1.
> {code:groovy|title=Main.groovy}
> import com.foo.Person
> class Main {
> static void main(String[] args) {
> Person.PersonBuilder pb = Person.builder()
> println(pb.build())
> }
> }
> {code}
> Trying to use it without a static import yields {{unable to resolve class
> Person.PersonBuilder}}, which is another issue.
> 2. Let's add a static import
> {code:groovy|title=Main.groovy}
> import com.foo.Person
> import static com.foo.Person.PersonBuilder
> class Main {
> static void main(String[] args) {
> PersonBuilder pb = Person.builder()
> println(pb.build())
> }
> }
> {code}
> The code compiles, but fails with {{java.lang.NoClassDefFoundError:
> PersonBuilder}} when run.
> 3. Let's add {{@CompileStatic}}
> {code:groovy|title=Main.groovy}
> import com.foo.Person
> import static com.foo.Person.PersonBuilder
> import groovy.transform.CompileStatic
> @CompileStatic
> class Main {
> static void main(String[] args) {
> PersonBuilder pb = Person.builder()
> println(pb.build())
> }
> }
> {code}
> Compilation fails with:
> {{Cannot assign value of type com.foo.Person$PersonBuilder to variable of
> type PersonBuilder}} and {{Cannot find matching method PersonBuilder#build()}}
