Intune Plugin fails when we use shared modules between androidTest and test

[shubhamgarg1]

Describe the bug: Android allows creating shared modules which can host code that can be called from androidTest and test source sets. When we create the same and add a dependency of app module in the sharedTest module, the tests inside androidTest module start failing.

To Reproduce Steps to reproduce the behavior:

1. Clone this repository https://github.com/shubhamgarg1/IntuneCodeCoverageNotWorking/tree/intune_plugin_fails_with_shared_test_module
2. Run ExampleTest inside androidTest folder of app Module and see the crash.

Expected behavior: The application should not crash.

Screenshots and logs:

Intune App SDK for Android (please complete the following information): -What version of the Intune SDK are you using? Are you using the latest version? Yes -What platform is your app based in (Java, Xamarin based, Cordova, etc)? Java -For errors during build, does the app build without Intune SDK integration? No -For errors post build, does the app launch without being Intune SDK integrated? No -Who is the customer? Adobe -Do you see a trend with it only being reproduced on a specific device? No

Additional context: It does not crash when we don't apply the intune plugin in the app module.

Hello, Thanks for the report. This is a known issue, tracked internally by #17339673. Does using the new build plugin (9.4.0) help? This uses a higher version of the Gradle plugin which may help this issue.
