Flag --emitDeclarationOnly not working with tsc --build

[frags51]

Bug Report

We have a project with references (composite = true). I want to watch over the project and just emit declarations files and no JS. --emitDeclarationOnly is mentioned as compiler options in the TS CLI doc, but it does not seem to be working with --build:

error TS5072: Unknown build option '--emitDeclarationOnly'. Since it is mentioned as compiler options, I am assuming this is unexpected behavior. VS Code is able to provide us with type checks - does it generate JS for all files?
