bundle

does a lot more than compilation, it packs e.g. all the resources that the target depends on into a single jar, including anything specified with the

bundles

keyword argument (e.g. for

jvm_app()

targets). if you bundle a lot of other files into a

jvm_app()

target, just copying and compressing those could take some time. i also don't believe the output of

bundle

is cached, since the output is usually just to a file in the

dist/

directory (which will be created if it doesn't exist). there's no reason it couldn't be, though -- what are you using the

bundle

goal for? if you haven't yet, i'd check out this page on the docsite (https://www.pantsbuild.org/jvm_projects.html#jvm_bundles)
