Did you try viewing the build log? This is probably the closest to what you want to see. You view the output window, and where it says "Build log was saved at "path..."", ctrl-click on "path" and it will open the build log.

Yes - this is the closest thing. It doesn't echo the complete command line, but only all the args. Good enough.
