Android Studio Build Works but Tests Fail with Duplicate Classes Error

I'm able to run the app on my Pixel 4 API 29 AVD, but when I try running tests, I see this error about duplicate dependencies used in jetified-checker-3.1 and jetified-checker-qual-3.13.0:

Execution failed for task ':app:checkStandardDebugAndroidTestDuplicateClasses'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable

The output after this error lists many "Duplicate class org.checkerframework.someClass". For example:

> Duplicate class org.checkerframework.checker.compilermsgs.qual.CompilerMessageKey found in modules jetified-checker-3.1 (org.checkerframework:checker:3.1.1) and jetified-checker-qual-3.13.0 (org.checkerframework:checker-qual:3.13.0)

Stack Overflow says to either add "android.useAndroidX=true" and "android.enableJetifier=true" settings in gradle.properties, which I see is already done, or to choose one of the conflicting classes to exclude.

Is there another setting I'm missing? Or, which of the modules' classes should I exclude?

My test settings seem to match the wiki developer guide:

Thanks,

Hi,

Please post questions like this as a support / discussion ticket to github. I don't think developers follow this list closely (even for me this email went to spam folder).

Does it work for you when you run tests from command line via gradle, i.e. ./gradlew testStandardRelease ?

Sure, I'll post as GitHub tickets from now on.

For this one, since it does work using command line, I think that's fine! I just wasn't familiar with Android testing.
