leiningen In Linux, use home from ${HOME} and not the current source for .m2 location

Given the behaviour observed below, I'm assuming leningen is obtaining the user's home from getent or similar path instead of relying (or even considering) ${HOME}.

Using a docker container with an arbitrary runtime user, the following behaviour is observed:

When the user exists in the container (i.e. nobody):

container invocation: docker run -ti --rm -v "${PWD}:/build" -w /build clj-builder:latest
executing lein install will (try to) download dependencies to: <user's home>/.m2

Expected failure due to perms in /:

bash-5.0$ id
uid=65534(nobody) gid=65534(nobody)
bash-5.0$ getent passwd $(id -u)
nobody:x:65534:65534:nobody:/:/sbin/nologin
bash-5.0$ echo ${HOME}
/build
bash-5.0$ pwd
/build/source/test
bash-5.0$
bash-5.0$ lein install

This could be due to a typo in :dependencies, file system permissions, or network issues.
If you are behind a proxy, try setting the 'http_proxy' environment variable.
bash-5.0$ exit

When the user DOES NOT exist in the container (i.e. nobody):

container invocation: docker run -ti --rm -v "${PWD}:/build" -w /build --user ${UID}:${UID} clj-builder:latest
executing lein install will download dependencies to the following path: <current_dir>/?/.m2
