Android instrumentation test fails with error when running cp command with --sparse option

[anuchandy]

Description of the problem / feature request:

I'm trying to run instrumentation test with following command:

sudo bazel test //contoso-common/src/androidTest/java/com/contoso/common:contoso_common_lib_instrumentation_test  --config=local_device --incompatible_disable_deprecated_attr_params=false --incompatible_new_actions_api=false --host_force_python=PY2 --incompatible_use_python_toolchains

This fails with error:

----------------

I'm using Mac and the cp command does not have --sparse option.

What operating system are you running Bazel on?

macOS Mojave

What's the output of bazel info release?

release 0.29.1

[jin]

android_instrumentation_test isn't supported on macOS.

Closing as dupe of #7069

[jinchizhou]

@jin what exactly isn't working in android_instrumentation_test? We're deciding if it is a better idea to use your composer_instrumentation_test or fix android_instrumentation_test.

Mostly the test runner (dexdump is compiled for linux only, with no plans to make it multiplatform), and the emulator infrastructure (unified_launcher).

For now, please consider alternatives like my experimental rules or you'd have to roll your own.
