> @NamedVariant processing error
> ------------------------------
>
> Key: GROOVY-8637
> URL: https://issues.apache.org/jira/browse/GROOVY-8637
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Reporter: Alexey Afanasiev
> Assignee: Paul King
> Priority: Critical
> Fix For: 2.5.1

>
> Example about @NamedVariant from
> http://groovy-lang.org/releasenotes/groovy-2.5.html works perfectly well as
> far as all @NamedDelegate type are compiling in the same compilation unit.
> {code:java}
> class Animal {
> String type, name
> }
> @ToString(includeNames=true)
> class Color {
> Integer r, g, b
> }
> @NamedVariant
> String foo(String s1, @NamedParam String s2,
> @NamedDelegate Color shade,
> @NamedDelegate Animal pet) {
> "$s1 $s2 ${pet.type?.toUpperCase()}:$pet.name $shade"
> }
> {code}
> But let's modify this example. If you have Animal an Color classes compiled
> beforehand and passed to the compiler with classpath, you will receive 'Error
> during @NamedVariant processing. Duplicate property 'metaClass' found.'
> NamedVariantASTTransformation treats 'setMetaClass' method as set method of
> some property with ''metaClass' name. Obviously these names are clashed at
> compile time.
