Docker support for linux/arm/v7

[davidmosna]

When building on RPi4 I got the following message

Sending build context to Docker daemon  22.42MB
Step 1/21 : FROM maven:3-jdk-11 AS scratch
3-jdk-11: Pulling from library/maven
no matching manifest for linux/arm/v7 in the manifest list entries

Would it be possible to modify the docker image build process so that all dependencies support linux/arm/v7 platform?

Apparently the maven Docker image does support ARM v8, just not v7. Too bad.

It is certainly possible to use a vanilla image of some Linux distro that supports both 7 and 8, download Maven into it, and perform the same job. However, it is not on the immediate list of priorities for me.

Contributions are welcome!
