i think that the PR might still be the best documentation though, unfortunately: https://github.com/pantsbuild/pants/issues/5360

the definitions of options are on

./pants help-advanced compile.zinc

and

./pants help-advanced java

but actually...

for options you want on all targets, you just want

--compile-zinc-args

. you're likely seeing that warning because you changed the value of

--compile-zinc-whitelisted-args="{'key1':val1,'key2':val2,...}" (default: { '-S.*':'False','-C.*':'False','-file-filter':'True','-msg-filter':'True' })
    A dict of option regexes that make up pants' supported API for zinc. Options
    not listed here are subject to change/removal. The value of the dict
    indicates that an option accepts an argument.

perhaps?

oh. or because that's just an invalid arg, and so it's not matching the regex
