Error when using the new multi-arch Paketo buildpacks

[ThomasVitale]

The Paketo Buildpacks project is now publishing multi-arch buildpacks for Java and Java Native Image. They both works great to containerize Spring Boot applications (3.2.5, 3.3.0-M1, 3.3.0-SNAPSHOT) when using the pack CLI.

However, when using the Spring Boot plugin (Gradle or Maven), the build only works on ARM64 architectures whereas it gets stuck indefinitely when running on AMD64 architectures (at least on Linux. I hope I'll get to test this on Windows as well and update this issue with more info).

I have created a repo with two examples to demonstrate the problem: https://github.com/ThomasVitale/buildpacks-demo.

> Task :bootBuildImage

The task gets stuck after pulling the buildpack image. It will only stop when forcefully shut down (on GitHub Actions that happens after 6 hours by default).

It works on my machine, though. Both projects work fine with g bootBuildImage.

Thanks @mhalbritter for the feedback. I've done some more testing. I have tried the following scenarios and they all worked fine, based on Docker Desktop 4.30.0 (Docker Engine 26.1.1).

• macOS (ARM64)
• Windows 10 (AMD64)
• Ubuntu 22.04 on WSL2/Windows 10 (AMD64)

I get the error in the following scenarios. I wonder if it's something related to the older Docker version or something specific to the VM images used by GitHub.

• ubuntu-22.04 GitHub Runners using Docker Engine 24.0.9 (example: https://github.com/ThomasVitale/supply-chain-security-java/actions/runs/9038631465/job/24840127488). Runner configuration: https://github.com/actions/runner-images/blob/main/images/ubuntu/Ubuntu2204-Readme.md
• Ubuntu 20.04 on GitHub Codespaces using Docker Engine 24.0.9 (it can be tested from this repo: https://github.com/ThomasVitale/buildpacks-demo).

[mhalbritter]

Thanks for the feedback. The failures on CI are reproducible, and not some flaky internet connection, right?

[ThomasVitale]

@mhalbritter yes, the failure on GitHub Actions (Ubuntu 22.04) and GitHub Codespaces (Ubuntu 20.04) is reproducible and happens consistently.

[ThomasVitale]

I also tried the build on newer GitHub runners (Ubuntu 24.04, Docker 26.1.0) and the outcome is the same: the build hangs indefinitely. Example: https://github.com/ThomasVitale/supply-chain-security-java/actions/runs/9059907830/job/25092379764
