Motivation
Fixes #6534
Fixes micronaut native image generation (on basic examples) by honouring the override configurations and using a better alternative (
-H:ConfigurationFileDirectories=) to pass the reachability metadata configs.For a more detailed explanation see this issue
Solution
Reachability metadata may provide override flags. These suggest that something needs to take precedence over something else. I didn't find a direct recommendation in any of the docs, but, I pulled out the native-image command gradle uses and found 6
--exclude-configflags on 6 netty artifacts.After some trial and error, I replicated the result using this override logic. For more information on the reverse engineering part see my comment here
Micronaut
Micronaut, also has AOT. I focused on the GraalVM support in this PR, so I haven't added direct support to Micronaut's AOT yet. But I've provided an example, which shows how it can be added by the user.
A future PR may provide a similar module to SpringBootModule with all the utilities given out of the box.
I haven't added much in this example yet, just that it builds.
Manual test:
I have also added support for including application resources in the native image from the module itself (ref: https://www.graalvm.org/22.1/reference-manual/native-image/Resources/)
Other fixes
With the changes to fetch artifacts, the kotlin native fails due to ignoring the resolution parameters. A fix was added in the coursier module to pass resolutionParams on.
