// There's an interaction between Gradle's resolution of dependencies with different types
// (@jar, @aar) for `implementation` and `testImplementation` and with Android Studio's built-in
// JUnit test runner. The runtime classpath in the built-in JUnit test runner gets the
// dependency from the `implementation`, which is type @aar, and therefore the JNA dependency
// doesn't provide the JNI dispatch libraries in the correct Java resource directories. I think
// what's happening is that @aar type in `implementation` resolves to the @jar type in
// `testImplementation`, and that it wins the dependency resolution battle.
//
// A workaround is to add a new configuration which depends on the @jar type and to reference
// the underlying JAR file directly in `testImplementation`. This JAR file doesn't resolve to
// the @aar type in `implementation`. This works when invoked via `gradle`, but also sets the
// correct runtime classpath when invoked with Android Studio's built-in JUnit test runner.
// Success!
