How do I tell pants that a non-zero exist code is ok (from an external tool) and prevent things from blowing up? Context: https://github.com/pantsbuild/pants/pull/13063 I am seeing this in an integration test, this is a legit lint failure but I get an exception instead:

pants.engine.internals.scheduler.ExecutionError: 1 Exception encountered:
E           
E           Engine traceback:

You use

Get(FallibleProcessResult, Process)

instead of

Get(ProcessResult, Process)
