AOSP build error: unrecognized module type "hidl_package_root"

Question

I'm keep getting that error in soong, while trying to build aosp.

When I type make, this is the output:

I've tried it with aosp_x86_64-eng, aosp_arm-eng and sdk_phone_x86_64_64, but I'm keep getting the same error. I'm using ubuntu 19.10.

When I type lunch, it also says that: Warning: Cannot display lunch menu.

Android 10 uses older Android.bp system that does not support some things newer AOSP version Android.bp supports.

try building your Android.bp with the latest AOSP once.
