When using BuildKit (which IIUC is currently the default), the built image does not list the FROM image as its parent in docker inspect metadata, and the FROM image is not even present in docker image ls -a, so the test doesn't work at all. dockerFingerprintFrom doesn't run by default as of #180, so I could also see an argument for just deleting the whole test file at this point.

" def built = docker.build('my-tag') \n" +
" dockerFingerprintFrom dockerfile: 'Dockerfile', image: 'my-tag' \n" +
" echo \"built ${built.id}\"\n" +
" }\n" +
"}";

assertBuild("build", script, BUSYBOX_IMAGE);

3-alpine hasn't been updated for around 5 years, and for whatever reason mvn hangs in the container running from the pulled image (but not in the container running from the built image). I suspect it has something to do with QEMU emulation since I am using an M1 Mac, but I really have no idea. I switched to 3-jdk-8-slim, which is actively maintained and has native arm64 builds, and the test passes locally now.
