Is there a way to clean up pants related folders? For example, my ~/.cache/pants folder is around 7.0G.

Just manual deletion for now. The issue to follow is https://github.com/pantsbuild/pants/issues/11167 In particualar - for manual deletion: •

rm -rf ~/.cache/pants/named_caches

will just make Python requirement resolution slower (The Pex cache is under there). • `rm -rf ~/.cache/pants/lmdb_store`will force Pants to re-run any subprocess it uses to produce results (run a test that's already been run green, typecheck a file whose contents have not changed since a past check, etc.).

yep! see also: https://www.pantsbuild.org/docs/using-pants-in-ci#directories-to-cache
