[jira] [Commented] (GROOVY-8825) CLONE - Conflict between
@Generated and @Delegate
[ https://issues.apache.org/jira/browse/GROOVY-8825?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16966379#comment-16966379 ]
Basil Peace commented on GROOVY-8825:
-------------------------------------
I have the similar issue with Gradle.
Class with method/property marked with {{@Delegate(methodAnnotations = true)}} can't be instantiated by Gradle (as task or extension), with error:
{noformat}
Caused by:
org.gradle.internal.instantiation.ClassGenerationException: Could not generate a decorated class for class org.fidata.gradle.svgo.Svgo.
...
Caused by:
java.lang.annotation.AnnotationFormatError: Duplicate annotation for class: interface groovy.transform.Generated: @groovy.transform.Generated()
at org.gradle.internal.instantiation.AbstractClassGenerator$DisabledAnnotationValidator.validateMethod(AbstractClassGenerator.java:1186)
at org.gradle.internal.instantiation.AbstractClassGenerator.inspectType(AbstractClassGenerator.java:255)
at org.gradle.internal.instantiation.AbstractClassGenerator.generateUnderLock(AbstractClassGenerator.java:191)
... 33 more
{noformat}
I'm not sure whether Gradle uses Groovy's code or has its own. But maybe this could help to reproduce.
