// The Art tests we use for R8 are pre-build and downloaded from Google Cloud Storage.
//
// To build and upload a new set of the Art tests for use with R8 follow these steps:
//
// First of all an Android checkout is required. Currently it must be located
// in $HOME/android/master.
//
// TODO(ricow): simplify this
//
// Before: update the checked in art, see scripts/update-host-art.sh
//
// 1. Get an android checkout in $HOME/android/master and apply the patch from
//    https://android-review.googlesource.com/#/c/294187/
//
// 2. run the following commands in the Android checkout directory:
//
//    source build/envsetup.sh
//    lunch aosp_angler-userdebug # or lunch aosp_angler-eng
//    m desugar
//    m -j30 test-art-host
//    DESUGAR=false ANDROID_COMPILE_WITH_JACK=false art/test.py --host -t 001-HelloWorld
//
//    Without running the test.py command the classes.jar file used by desugar in
//    $HOME/android/master/out/host/common/obj/JAVA_LIBRARIES/core-oj-hostdex_intermediates/
//    seems to be missing - there is probably also a make target to build it more directly
//
// 3. In the R8 project root directory, make sure we have a clean state before starting:
//    tools/gradle.py downloadDeps
//    tools/gradle.py clean
//    rm -rf tests/art
//
// 4. Now build in the R8 checkout (-P hack to not generate dirs when not running this target)
//    Make sure you have smali on your path, please use the build binary in the
//    out/host/linux-x86/bin directory of the android checkout. Currently this is version pre 2.2.1,
//    if that is updated the call to smali in "task "${smaliToDexTask}"(type: Exec)" below might
//    need to change as smali got a completely new command line interface in version 2.2.1.
//    After Android O, Jack is no longer alive, do not forget to uncomment call to buildArtTest for
//    Jack if you build an android version using Jack.
//
//    PATH=$HOME/android/master/out/host/linux-x86/bin:$PATH tools/gradle.py -Pandroid_source buildArtTests
//
// 4a. If any failures are produced in step 4, figure out what went wrong and add an entry in
//     skippedTests with an explanation. Rerun from step 3.
//
// 5. Run the tests:
//    tools/gradle.py clean
//    tools/test.py
//
// 5a. If any more tests fail, either fix the issue or add them to the failuresToTriage list (note
//     that you need to change "_" to "-" from stdout). Rerun from step 5 if anything was added to
//     failuresToTriage.
//
// 6. To upload a new version to Google Cloud Storage:
//    cd tests
//    upload_to_google_storage.py -a --bucket r8-deps art
//
// 7. Update the manifest file describing the Android repo used:
//    repo manifest -o <r8-checkout-root>/tools/linux/aosp_master_manifest.xml -r
