> Key: GROOVY-10937
> URL: https://issues.apache.org/jira/browse/GROOVY-10937
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 4.0.9
> Reporter: Marcin Zajaczkowski
> Assignee: Eric Milles
> Priority: Minor
> Fix For: 4.0.10

> I've bumped into a strange looking compilation error in a project using JDK
> 17 record, Lombok's @NotNull and Groovy for tests. It took me a while to find
> a construction which causes that, as:
> # Compilation error occurs in a Groovy class not related to the problematic
> Java record.
> # Groovy class must have (non related) inner interface or class.
> # Record has must have two (or more) fields with @NotNull annotation from
> Lombok.
> # Some (other) Groovy class has to refer to that record.
> For example:
> {code:java}
> // Java
> public record SampleRecordWithNonNullFromLombok(
> @NonNull
> String nonNullField,
> @NonNull //Two or more @NulNull annotated fields are required
> to trigger the problem
> String nonNullField2
> ) {}
> //Groovy
> class ClassWithReferenceToRecord {
> private SampleRecordWithNonNullFromLombok sampleRecord
> }
> class ReproducerClass { //it fails to compile
> interface RequiredToReproduceProblem {
> }
> }{code}
> The error is:
> {code:java}
> [ERROR] Failed to execute goal
> org.codehaus.gmavenplus:gmavenplus-plugin:1.13.1:compileTests (default) on
> project record-lombok-groovy: Error occurred while calling a method on a
> Groovy class from classpath.: InvocationTargetException: startup failed:
> [ERROR] .../ReproducerClass.groovy: -1: Cannot specify duplicate annotation
> on the same member : lombok.NonNull
> [ERROR] @ line -1, column -1.
> [ERROR] 1 error
> {code}
> I created a shrank version of a reproducer:
> [https://github.com/szpak/code-examples-and-poc/tree/master/record-lombok-groovy]
>
> It might be a problem with the way how Lombok generates .class for Java
> record, however, I start here as Groovy compilation is the final reason.
> I have observed that error occasionally with Groovy 3(.0.14), but it occurs
> every time with 4(0.9).
