Android Unit tests using library resources fail when run from command line

SUMMARY:

Two modules, android application module and an android library module. Unit test for Application module calls static method on class from Library module that returns resource id of resource defined in Library. Unit test fails on this call with "Caused by: java.lang.ClassNotFoundException: com.example.librarybase.R$string", but only when run from command line (gradlew test). Unit tests pass when run from Android Studio.
