This repository provides a BuildImageTest that uses the buildpack to create a native image. It then tests the native image, using Testcontainers and JUnit. Building the native image with AOT processing, as part of a test, takes minutes not seconds, and should not be part of normal "inner loop" development. So the BuildImageTest is in a separate sourceSet and can be executed independently. This is a very powerful pattern, that I'm just getting started with. I would love to hear your thoughts on this pattern or other alternatives to it.
Today, the buildpack delivered by Spring Initializr at start.spring.io, is unable to create native images on ARM64.

Spring Framework 6 and Spring Boot 3.0.0 have recently gone GA. My favorite feature of these new releases is hands down the AOT processing. The AOT processing, provided by GraalVM, creates statically linked binary images. These images are optimized, ahead of time, for the operating system and architecture. For many modern workloads they can provide smaller image sizes, smaller memory footprint, and a much faster startup time.
In a recent experiment, I was able to expose Spring Cloud Gateway to the public, and have it route to other Spring Boot 3 native image workloads.
