The process to cross compile to arm64 does not works

On Page: Build for ARM architecture

I am running it on a x86_64 arch, trying to build a arm64 image, if I run this command inside a OrangePi, it's run fine.

$ pack build java-maven-sample --path samples/apps/java-maven/ --builder heroku/builder:24 --platform linux/arm64

Thanks for this. Right now buildpacks will build an image that is the same as the architecture you're running on. We don't yet support building arm64 on an amd64 machine (or vice-versa). Leaving this open so that we add an explanatory note to that documentation page.
