Test app showing off issues running tests via Android Studio in some configurations
See https://issuetracker.google.com/issues/281266702
Running AGP 7.4.2, which is setup in the master branch, you'll see that test_sample_class test passes successfully with no errors reported in console.
Switching to the latest-agp branch, which upgrades AGP to the latest AGP version the same test_sample_class test passes, but errors related to JaCoCo are printed out:

If I set enableAndroidTestCoverage to false and/or remove this config entirely, the tests pass and no errors are reported, but this value is required for jacoco coverage (which I did not setup for this test, since the issue lies in running tests via Android Studio).
Update 11/2/23: It appears that this issue has been fixed in a recent alpha version of AGP 8.3.0!
