Are you suggesting that i make a lein deps to a local m2 folder and then upload it as a whole to, say, an s3-bucket? I was thinking there would be some batch operation like lein deps and then lein install-all-deps-into-a-certain-private-repo , but if not, uploading the resulting folder would certainly work, albeit with some extra work when upgrading dependencies. I guess the most common way of solving this is to use a maven mirror that works a proxy. Thanks!

lein treats the cache as a cache, and doesn't have commands for manipulating it (other than downloading new items that aren't yet present, or installing from a local artifact into the cache)
