The top directory of AOSP is ~/WORKING_DIRECTORY. If I run
~/WORKING_DIRECTORY$ make
the whole system builds correctly.
According to Building a particular module in the android source code, https://stackoverflow.com/a/30671099/746461, if I need to rebuild art, I will
cd art
mm
However it throws error:

If I stay in ~/WORKING_DIRECTORY and call mm art, it seems to build correctly.
However, if I deliberately make a mistake in the source code, then run
~/WORKING_DIRECTORY$ mm art
it still builds, which means the new files are not compiled at all. See the screenshot.
What's the correct way of rebuilding a module?
