org.mockito.internal.util.reflection.FieldSetter; deprecated in mockito-core 4.3.1

In the below code FieldSetter.SetField was used for the test case but now as I have up upgraded to mockito-core 4.3.1. This no longer works. Can you please suggest to me what can I replace it with?

This is throwing an error as it is deprecated in mockito 4.3.1

import org.mockito.internal.util.reflection.FieldSetter;

@Rule
public AemContext context = new AemContext();
private FareRulesRequestProcessor fareRulesRequestProcessor = new FareRulesRequestProcessorImpl();
private FareRulesPathInfo pathInfo;
@Mock
private SlingHttpServletRequest mockRequest;
private FareRulesDataService mockFareRulesDataService;
@Before
public void before() throws Exception { mockFareRulesDataService = new FareRulesDataServiceImpl(); mockFareRulesDataService = mock(FareRulesDataService.class); PrivateAccessor.setField(fareRulesRequestProcessor, "fareRulesDataService", mockFareRulesDataService);
}
@Test
public void testFareRulesDataForRequest() throws NoSuchFieldException { when(mockRequest.getPathInfo()).thenReturn(FARE_RULES_PAGE_URL); FieldSetter.setField(fareRulesRequestProcessor, fareRulesRequestProcessor.getClass().getDeclaredField("validFareRulesDataMap"), getFareRulesDataMap()); FareRulesData fareRulesData = fareRulesRequestProcessor.getFareRulesData(mockRequest); assertEquals(FROM, fareRulesData.getDestinationFrom()); assertEquals(TO, fareRulesData.getDestinationTo()); assertEquals(MARKET, fareRulesData.getMarket()); assertTrue(fareRulesData.isFareRulesByMarket());
}

This was an internal class of Mockito, you should not depend on it. I ended up using this simple util instead:

//import java.lang.reflect.Field;
public class ReflectUtils { private ReflectUtils() {} public static void setField(Object object, String fieldName, Object value) { try { var field = object.getClass().getDeclaredField(fieldName); field.setAccessible(true); field.set(object, value); } catch (NoSuchFieldException | IllegalAccessException e) { throw new RuntimeException("Failed to set " + fieldName + " of object", e); } }
public static void setField(Object object, Field fld, Object value) { try { fld.setAccessible(true); fld.set(object, value); } catch (IllegalAccessException e) { String fieldName = null == fld ? "n/a" : fld.getName(); throw new RuntimeException("Failed to set " + fieldName + " of object", e); }
}
}
