Add option to remove cache after build

[herbertjones]

Would it be possible to add an option to remove all files except the built binary? For instance in Rust for even a simple script runs over 100MB, but the built binary is only a megabyte or two. Writing several small scripts can become very wasteful.

For instance, a new configuration option field named clean_cache_after_build which removes all cache files except the target_bin could be added so that excessive disk space isn't wasted.

This could also be done manually by updating all scripts with a custom build_cmd. Might still be a useful option though.

// build_cmd: cargo build --release && strip ./target/release/script && rm -rf ./target/release/deps && rm -rf ./target/release/build

It looks like this is very language specific. Here are few examples when this does not work as expected:

• Build produced multiple files require for the program to work. target_bin is just a starter script.
• The majority of space is occupied outside of the cache dir
  • ~/.cargo, ~/.m2, and other caches of package managers
  • Docker layers and volumes

Is there really a reliable way to determine all transient files that were produced for all languages, warranting this a first class feature?

Probably just having a cleanup_comand option is better, but that benefit is still marginal.

Thoughts?

Sounds like it isn't worth the effort then.
