ManPageGenerator fails with Quarkus

[svartkanin]

I'm using picocli successfully with Quarkus but now wanted to use the ManPageGenerator command as well.

@Command(
    name = "documentation",
    description = ["Command to generate CLI documentation"],
    subcommands = [ ManPageGenerator::class]
)
class Documentation

However, running building the executable and running it leads to the error

 ERROR [io.qua.run.Application] (main) Failed to start application (with profile [prod]): picocli.CommandLine$InitializationException: Could not access or modify mixin member picocli.codegen.docgen.manpage.ManPageGenerator$Config picocli.codegen.docgen.manpage.ManPageGenerator.config: java.lang.NoSuchMethodException: picocli.codegen.docgen.manpage.ManPageGenerator$Config.<init>()

Sorry I dropped the ball on this...
I just created a test without Quarkus, that seems to work fine.
This seems to be a Quarkus issue. Have you asked the Quarkus maintainers about this issue?
