Consider this scenario:

1. You have expansion-deps.projitems which contains the @(JdkIncludePath) item group.
2. You have expansion.props which uses @(JdkIncludePath) to generate a $(_JdkIncludePaths) property
3. You have expansion.projitems which creates a new @(_HostRuntime) item group which uses $(JdkIncludePath) within the %(_HostRuntime.CFlags) item metadata
4. You print out %(_HostRuntime.CFlags).

Incredibly, behavior differs between xbuild, msbuild in mono 4.6, and msbuild in mono 4.8.

Android NDK, SDK

Note: A xamarin-android checkout maintains its own Android NDK + SDK to ensure consistent builds and build behavior, permitting reproducible builds and providing greater flexibility around when we need to perform Android SDK + NDK updates. The Android SDK and NDK are maintained by default via two directories in your home directory:

• $(AndroidToolchainCacheDirectory): Where downloaded files are cached. Defaults to the $HOME/android-archives directory.
