Tobias Thierer f795dcb767 Experimental feature: LOCAL_PATCH_MODULE option in .mk files.
Specifying this option causes the make target's sources
and classpath dependencies to be patched into the specified
module via --patch-module (if the build toolchain implements
the module system, ie. when targeting 1.9). This allows tests
to compile that have classes in packages under test.

Currently, only java.base is on the module path (everything
else is on the classpath), and only when using -target 1.9
(ie. EXPERIMENTAL_USE_OPENJDK9=true).

Bug: 71699916
Test: Treehugger
Test: Checked that I was able to compile some ojluni & icu
      test sources that had classes in (libcore) packages
      under test.

Android Make Build System

This is the Makefile-based portion of the Android Build System.

For documentation on how to run a build, see Usage.txt

For a list of behavioral changes useful for Android.mk writers see Changes.md

For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.

This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
