Consider adding a Dockerfile that doesn't declare the .m2 directory as a volume

[aslo]

Child images are unable to remove the VOLUME declaration for this directory, and this means that pre-cached maven artifacts need to be copied into this directory at container start time.

When many artifacts are cached, this can take a long time, and it's on the critical path of performing a maven build with this container. It would be nice to be able to just pre-download artifacts directly into the .m2/repository directory.

That was discussed in #11

You can use -Duser.home= to point to another dir

[aslo]

Ok, that's a reasonable solution. Thanks!
