Paul King commented on GROOVY-8803:
-----------------------------------
Currently resolution occurs before the @Builder transform runs. This isn't
normally a problem since either you are using the normal modes of usage where
the builder class name is effectively a hidden detail or you are compiling your
builder separately from usage as part of a build system. Perhaps it could be
extended to cover additional modes of operation. To get everything within one
script (I tried with 2.5.9 and 3.0.1), you could try something like:
{code}
import groovy.transform.builder.Builder
@Builder
class Foo {
String bar
}
new GroovyShell(getClass().classLoader).evaluate '''
Foo.FooBuilder aBuilder = Foo.builder()
assert aBuilder.class.name == 'Foo$FooBuilder'
assert aBuilder.methods*.name.contains('setBar')
class FooBuilderExtension extends Foo.FooBuilder {}
def foo = new FooBuilderExtension().builder().bar('baz')
assert foo.bar == 'baz'
class Bar {
@Delegate Foo.FooBuilder builder
}
assert Bar.methods*.name.contains('build')
'''
{code}
> Can't refer class declared with @Builder annotation

> Key: GROOVY-8803
> URL: https://issues.apache.org/jira/browse/GROOVY-8803
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.5.2
> Reporter: Tomasz Przybysz
> Priority: Minor
>
> The following fails to compile:
> {code:java}
> import groovy.transform.builder.Builder
> @Builder
> class Foo {
> String bar
> }
> Foo.FooBuilder aBuilder = Foo.builder()
> {code}
> The compile error is:
> {quote}Error:(8, 16) Groovyc: unable to resolve class Foo.FooBuilder
> {quote}
> I'm not sure if it's a bug. Although seems it should be possible to refer a
> `@Builder` generated class as any other.
