GraalVM native image build with mixinStandardHelpOptions is missing a reflect-config entry about picocli

[mfuerstenau]

Can confirm. I have no subcommand defined but I encounter this issue in Windows and Linux. Maven 3.8.4, picocli 4.7.5. Main class entry is present but Mixin class entry is missing. Manually adding it fixed the issue.

@itzg You wrote "when it works", did it on occasion work for you?

Thank you both for raising this!

@mfuerstenau you mentioned that you are able to reproduce the issue in a top-level command without subcommands; can you provide more details to help me reproduce the issue? (How many options, does the command have positional parameters, other mixins, ...)

@mfuerstenau I just meant when there is only one option field declared then the mixin class got auto-discovered and captured in the reflect json. When there were two options, it didn't.

I found what is causing my issue: the second option in my command class is named "version", which overlaps with the standard help options. At this point the mixin is not added to the outer ComandSpec:

This now seems a self-inflicted issue, so I'm good with closing this issue if it seems like outcome matches expectations.
