@wide-energy-11069 is right, but it sounds like only @aloof-angle-91616 has the tool at this point. So, yes, you can just correctly place it under

~/.cache/pants

, or - slightly more robust - just add a local directory path to the baseurls list:

jsirois@gill ~/dev/pantsbuild/pants (master) $ ./pants options --scope=GLOBAL --name=binaries_baseurls
binaries_baseurls = ['<https://binaries.pantsbuild.org>'] (from HARDCODED)

jsirois@gill ~/dev/pantsbuild/pants (master) $ PANTS_BINARIES_BASEURLS="/tmp/tool" ./pants options --scope=GLOBAL --name=binaries_baseurls
binaries_baseurls = ['<https://binaries.pantsbuild.org>', '/tmp/tool'] (from ENVIRONMENT from env var PANTS_BINARIES_BASEURLS)
