This test was moved to gradle_utils_test.dart and it now checks for the exact exception message.

I tried. Unfortunately, it doesn't render on PowerShell/cmd.exe. We could detect that or leave as is.

Seems like AndroidBuilder is mostly just a trivial wrapper around buildGradleAar and buildGradleApp now. Can we remove the entire file? (Maybe in a follow-up PR.)

+1. I filed #43863. Originally this was needed to test the build commands because the current build process is messy and requires mocking too many files/process calls, etc.

it would be cleaner if flutter was always called with an argument that did that, rather than relying on the environment variables.

+1. When the tool calls Gradle, it doesn't log analytics. However, in add2app scenarios, when a developer calls Gradle directly (from Android Studio, for example), it's preferred to log the calls to the tool.

Should much of the contents of gradle.dart also be in a GradeUtils-like class? (maybe GradleUtils itself?)

Is it possible to supply some advice here? Like, "Try again." or "Look up in the logs for your error message from the Java build." etc.

You could include the exit code in one of the other fields of the event if that would be useful.

Would a BuildEvent for this be useful?

This PR refactors
gradle.dart.Here's the summary of the two main changes:
First, running
flutter build apk/appbundle/aarinvolves 3 calls to Gradle. One to get the version, one to get the list of flavors and finally the last call to build the target artifacts. These calls add about 2s overhead to the build calls, but most importantly add complexity to the code. e.g. Caching ofstdoutis required, so tests don't time out.I'm essentially getting rid of that. Once this PR is merged, we will call Gradle only once to build the artifacts. We will only get the list of flavor if Gradle failed due to an undefined flavor set via the tool's
--flavorflag. This is the only use case for getting the list of flavors from Gradle.Second, we have logic to detect common Gradles errors that attempts to guide the user toward completing the journey. This logic is all over the place. Some code checks if an error is triggered when checking the Gradle version. Other code checks if an error is triggered when building the artifact.
I don't think this is necessary since these errors occur not matter when the call to Gradle is made. As a result, I organized these logic around a new data structured called
GradleBuildError, which makes it easier to add new error handler in the near future.
