Hi, I saw this today:

./pants test ::                                                       
Another pants invocation is running. Will wait up to 60.0 seconds for it to finish before giving up.
If you don't want to wait for the first run to finish, please press Ctrl-C and run this command with PANTS_CONCURRENT=True in the environment.

I was running

./pants repl ::

in another terminal. Anyways, I was able to get it to run by

PANTS_CONCURRENT=True ./pants test ::

. Was wondering why it isn’t default? Are there any issues which I should be aware of? Typically, have a repl in another shell is a common strategy

This is the issue tracking: https://github.com/pantsbuild/pants/issues/7654 I'm not sure that will help you much except to say that everyone wants this and there are known reasons why it can't happen quite yet.

do you see this issue effecting running the repl in another shell?
