How do I delete and redownload all my dependencies?

@dfcarpenter: this is not really lein related question, I think. Maven manages dependencies. You can wipe out your whole local repo ~/.m2, or delete individual folders

maybe there are mvn commands to do that more conveniently, but I’m no maven expert

That’s what I ended up doing. Thanks

I do that every few months to prune old versions of dependencies that are no longer used by anything. Probably not necessary but I like the sense of maintenance.
