Experiment with Cloud Native Buildpacks

[bobeal]

Tried on the feature/spring-boot-3 branch and it is possible to build an OCI image in this way.

However, the image built targets amd64 architecture and it does not seem to have an easy way to create multi-arch images as it is currently done for Stellio.

Found this: https://dev.to/dashaun/a-new-builder-for-spring-boot-3-rc1-on-arm64-4k31 but it failed when tested locally (is it only supposed to work when building native images?).

You are not the only person to report the builder isn't working.

I pushed out a new version, I've testing it on M1 and Oracle ARM64.

Please try with this configuration, to make sure you don't get a cached version:

                        <plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
				<configuration>
					<image>
						<builder>dashaun/builder:20230204</builder>
					</image>
				</configuration>
			</plugin>
