将Mockito测试从Junit 4迁移到Junit 5时出错

我正在尝试将Mockito测试从Junit 4迁移到Junit 5，方法是将@runwith(MockitoJUnitRunner.class)替换为@extendwith(MockitoExtension.class)，但这会导致以下错误。不知道我错过了什么，任何帮助都将非常感谢。

测试类：-

import org.junit.jupiter.api.Test;
    
import org.junit.jupiter.api.extension.ExtendWith;
    
import org.mockito.InjectMocks;
    
import org.mockito.Mock;

@ExtendWith(MockitoExtension.class)
    
public class LumpBookingCurveCalibratorTest {
    
     
   
   @Mock
       
   private ForecastLump forecastLump;
    
     
   
   @InjectMocks
        
   private LumpBookingCurveCalibrator bookingCurveCalibrator;
    
     

   @Test
       
   public void arrvlBookingCurveCalibratorSaveCalled() {
       
        ...     
   }
}

compile 'org.junit.jupiter:junit-jupiter:5.7.1'
    
compile 'org.junit.vintage:junit-vintage-engine:5.7.1'
    
testCompile 'org.mockito:mockito-junit-jupiter:3.9.0'

从Intellij运行测试时的错误日志：-

当你使用木星时，你必须移除修改器。至少这对我起作用了。

import org.junit.jupiter.api.Test;
        
import org.junit.jupiter.api.extension.ExtendWith;
        
import org.mockito.InjectMocks;
        
import org.mockito.Mock;

@ExtendWith(MockitoExtension.class)
        
class LumpBookingCurveCalibratorTest {
        
         
   
   @Mock

   @InjectMocks
            
   private LumpBookingCurveCalibrator bookingCurveCalibrator;
        
         

   @Test
           
   void arrvlBookingCurveCalibratorSaveCalled() {
           
        ...     
   }
}
