Routing to @dcharkes who added the test a couple weeks back. My suggestion for debugging the flake would be to land more debugging output from the
testPluginplugin method in that file. In particular, if a call toprocessManager.runSync()fails, it should print the exit code, stdout, and stderr from the subprocess.keyonghan commentedon Apr 8, 2022

@dcharkes ptal.

This time it is the platform-channel-plugin that is failing, not the FFI plugin.
And it is failing in the
flutterinvocation which is not run for the FFI plugins, so my last PR did not add extra prints there.Here's a PR which adds prints to the remaining invocations:

This issue happened twice in the past two days:
https://ci.chromium.org/ui/p/flutter/builders/prod/Windows%20tool_integration_tests_1_6/2256/overview
https://ci.chromium.org/ui/p/flutter/builders/prod/Windows%20tool_integration_tests_1_6/2271/overview
Bumping to P1.

@keyonghan both of those failures seem to be saying that the NDK on the bot is malformed. In one case the zip archive failed to be extracted correctly, and in the other, it was missing a file.
keyonghan commentedon Jul 22, 2022
Thanks @zanderso for the triage.
It is indeed with the bot. Both failures happened on https://chromium-swarm.appspot.com/bot?id=flutter-prod-windows-us-central1-a-11-fv9g, which seemed have caused tests failure across other tests.
I clicked
STOP THE BOT GRACEFULLY, and this bot should not be assigned to any tasks for today. Additionally, all bots will be auto re-provisioned tomorrowOn top of that, the original filed flaky issue is not reproducing.
I will monitor this bot issue a bit before closing.

Closing as this didn't repro.

I'm seeing this in a try bot: https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket/8765048998182417073/+/u/run_test.dart_for_tool_integration_tests_shard_and_subshard_1_6/test_stdout for the PR: #137878
dcharkes commentedon Nov 8, 2023
AGP downloads the NDK (the version it wants) on demand, so maybe some bits fell over on the network? I'm not really sure what to do about this.
(Side note: With the native assets,
--template=package_ffiinstead of--template=plugin_ffi, flutter_tools controls what NDK it uses for native builds: the NDK inside the Android SDK detected by flutter doctor. For our bots that means using the NDK from the CIPD package. So hopefully the new way of doing things will not have these kind of install-via-the-network flakes.)
