Expected Behavior

All information on https://youtrack.jetbrains.com/issue/IDEA-331174 as I initially believed this to be an Intellij-specific issue.

Example project included in this ticket:
groovy-compile-bug.zip

Actual Behaviour

Compilation fails when building Micronaut 4 groovy projects using Intellij's compiler, that have annotations that are defined in Groovy files.

Steps To Reproduce

All information on https://youtrack.jetbrains.com/issue/IDEA-331174 as I initially believed this to be an Intellij-specific issue.

They state that the problem is caused by the library io.micronaut:micronaut-inject-groovy starting from version 4.0.0, so raising it here for further investigation.

Environment Information

Operating System: MacOS Ventura, Version 13.4
JDK Version: Coretto 17

Example Application

see attached

Version

4.0.3

Reproducer:

// Annotation.groovy
import java.lang.annotation.ElementType
import java.lang.annotation.Target

@Target(ElementType.FIELD)
@interface Annotation {
}
// Usage.groovy
class Usage {
    @Annotation
    String field
}

Then

groovyc Usage.groovy Annotation.groovy -cp micronaut-inject-groovy-4.1.6.jar:micronaut-core-4.1.6.jar:micronaut-core-processor-4.1.6.jar:micronaut-inject-4.1.6.jar:jakarta.annotation-api-2.1.1.jar:jakarta.inject-api-2.0.1.jar:micronaut-aop-4.1.6.jar:asm-9.5.jar:asm-commons-9.5.jar

Results with

Invalid duplicate class definition of class Annotation : The sources file:/Users/_/Annotation.groovy and Annotation.groovy each contain a class with the name Annotation.

The problem is that io.micronaut.ast.groovy.annotation.GroovyAnnotationMetadataBuilder#getAnnotationMirror tries to find ClassNodes when there are none, and it results in generation of additional SourceUnit for Annotation. Maybe the annotation processing occurrs too early?

does it work when building with gradle? you should let intellij delegate build tasks to gradle

Please, configure your IDE according to USING INTELLIJ IDEA TO DEVELOP MICRONAUT APPLICATIONS and let us know if the issue is still present.

When I specify the Gradle option in the IDE setup it works, as specified on that link - this is the workaround I currently have to use for the project:

However, pre Micronaut 4 the Intellij compiler option worked as well, and makes for a much faster dev experience in terms of build and start times:

Looks like a bug in the IntelliJ compiler or the Groovy compiler. None of the methods we use is supposted to create an additional class.

Got a standalone script (just requires Groovy and Bash to be installed) to reproduce the issue

@dstepanov If I revert this PR #9232 the compilation passes, but I am not sure what is causing the problem

That is fixing some other stuff

Can you create a test inside the core?

@dstepanov Reproducer here: #9925

(this took more effort that it may seem from looking at it 😉)

Hey, is there any way of progressing this? As far as I can see it's still an issue in the latest Micronaut release
