KSP processing fails with Java enum

I found a few different exceptions:

Any news on this? I get this exact error following this example, but with a Kotlin application instead of Java: https://guides.micronaut.io/latest/micronaut-openapi-generator-server-gradle-java.html

Shame if the Micronaut OpenAPI server generator doesn't work with Kotlin.

@runenielsen The solution should be to put the Java classes into the Java folder

[runenielsen]

@dstepanov: Thanks, but the generated Java models are already in the path:

build/generated/openapi/generateServerOpenApiModels/src/main/java

... and this path is part of the Java source set of the application.

So they are already in a Java folder...

I thought for the people in the issue that is a workaround

[opaquot]

Hi. I'm having the same issue. Are there any news on this?

[pshemass]

any update on this?

[sgammon]

makes ksp unusable with protobuf

I have created a PR with a fix #1635
