on github actions there's a feature to store build cache to speed up future deployments.
the current tangled spindle pipeline uses docker image layers for cache, which works for system libraries, but in cases like gradle, which has its own build and configuration cache, this doesn't really work. when mixed with game modding plugins like fabric-loom, which for earlier versions of the game remapped game jars, or forgegradle which patches jars in source, this really adds up in workflow time.
