Daniil Ovchinnikov commented on GROOVY-9472:
--------------------------------------------
More general problem: there should be *zero* difference in compilation of file1
and file2 together in one run and file1 followed by file2 in two subsequent
runs (= two different compilation units). I've encountered this problem
multiple times. The problem hits incremental recompilation, when e.g. file1 is
unchanged, and we only want to recompile file2. I'm not sure how it works in
Gradle, but it's one major pita in IJ, e.g. in this particular case the first
compilation run would compile Person.groovy and fail with an error in
Main.groovy, then the next run would compile Main.groovy successfully, so users
come and ask why IJ cannot do it in one go.

> 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()}}
