// We run fairly hard into a fundamental limitation of the Android Gradle
// plugin. There are many bugs filed about this, but
// https://code.google.com/p/android/issues/detail?id=216978#c6 is a reason one.
// The issue is that we need fine-grained control over when to include Gecko's
// binary libraries into the GeckoView AAR and the Fennec APK, and that's hard
// to achieve. In particular:
//
// * :app:automation wants :geckoview to not include Gecko binaries (automation
// * build, before package)
//
// * :geckoview:withLibraries wants :geckoview to include Gecko binaries
// * (automation build, after package)
//
// * non-:app:automation wants :geckoview to include Gecko binaries (local
// * build, always after package)
//
// publishNonDefault (see
// http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Library-Publication)
// is intended to address this, but doesn't handle our case. That option always
// builds *all* configurations, which fails when the required Gecko binaries
// don't exist (automation build, before package). So instead, we make both
// :app and :geckoview both know how to include the Gecko binaries, and use a
// non-default, non-published :geckoview:withGeckoBinaries configuration to
// handle automation's needs. Simple, right?
// The omnijar inputs are listed as resource directory inputs to a dummy JAR.
// That arrangement labels them nicely in IntelliJ. See the comment in the
// :omnijar project for more context.
