Research direction

Start in packages/host/android/build.gradle around lines 141-157 and inspect how the Android build tasks are configured. Run an Android build without REACT_NATIVE_OVERRIDE_HERMES_DIR, then verify that it exits early with instructions using the provided npx react-native-node-api vendor-hermes command when the variable is missing.

Description

Android 🤖 good first issue

I've investigated ways of letting the host package drive building Hermes from (our) source. So far, I haven't found any.

In the absence of a fully automated solution, it would be good if we exist early with instructions on how to set the REACT_NATIVE_OVERRIDE_HERMES_DIR environment variable if missing:

export REACT_NATIVE_OVERRIDE_HERMES_DIR=`npx react-native-node-api vendor-hermes --silent`

I would expect the error to be thrown from a new task around here:
