Alternatively, is there a way to pass in a large argument list via text file? If I compute the list of transitive dependencies and run
./pants compile $TRANSITIVE_TARGETS
then the argument is too long

--target-spec-file

should that file contain line separated arguments?

sweet!
will pants be OK if I call
./pants compile ...
with thousands of targets?

you can use
diff
or
comm
to diff the output of
dependencies
and
list
but i assume you’ve figured that out
yes!!! i recommend gnu parallel to shard large target lists

I already ran pants export, so I have the list of transitive deps

but pants can be run with that
ok, that should work great!

@aloof-angle-91616 how exactly is the syntax?
/pants compile --target-spec-file=args.txt
?

yes, you may need to place it at the front of the command line. typically arguments immediately after a goal name such as
compile
are interpreted as options within the scope of that goal

I'm getting "Build graph construction failed"
I'll just compile everything, will try to figure out another time how to skip compiling the actual targets
Thank you for the help!

i’m sorry!! that usually happens when invalid target specs are added, or when a target’s definition is invalid (pants will lazily crawl the filesystem to parse BUILD files). if you post the stacktrace we can debug — sorry for the confusing error message!

It's fine, the approach to extract the dependency targets was quite hacky
compiling everything is working great for now, would be nice to avoid the redundant compilation in the future with
--query

it's possible i may be able to work on that earlier than expected if it's relevant for IDE responsiveness
