You can quickly create a new library with lein new default my-library-name.

But if you add a group-id to that, lein is smart enought to just use the artifact-id for the directory name, but the full maven id when installing to your local repository.

I thought I was having issues with using my-library-name vs. dev.andylu/my-library-name, but I can't reproduce the weird behavior now.

So I'm going to chalk it up to the usual "I don't own the ~/.m2 folder" and just run sudo chown -R "$USER":"$USER" ~/.m2 and forget about it.
