Mockito 2 + Junit 5 NoSuchMethodError on AnnotationSupport.findAnnotation

I'm trying to integrate JUnit 5 under Eclipse Oxygen3. The project already has Mockito 2.

I have done all steps suggested in https://www.baeldung.com/mockito-junit-5-extension like so:

Dependencies:

Code:

public class Jupiter {

    public boolean isAlpha() {
        return true;
    }

}

Test Code:

import static org.assertj.core.api.Assertions.assertThat;
import static org.mockito.BDDMockito.given; 
import java.util.Date;  
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.junit.platform.runner.JUnitPlatform;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.junit.jupiter.MockitoExtension;

@ExtendWith(MockitoExtension.class)
@RunWith(JUnitPlatform.class)
public class JupiterTest {

    @InjectMocks
    private Jupiter jupiter;

    @BeforeEach
    public void setup() {
        //usually some stuff here
    }

    @Test
    @DisplayName("heading jupiter - make it so")
    public void test() {
        boolean result = jupiter.isAlpha();

        assertThat(result).isTrue();
    }
}

Unfortunately, running tests fail.

Have anyone stumbled upon a similar problem? Is it something general or my project specific problem?

mockito-junit-jupiter 2.28.2 allows you to use this way, this may possibly solve your problem.

import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;
import org.mockito.InjectMocks;
import org.mockito.junit.jupiter.MockitoSettings;

import static org.assertj.core.api.Assertions.assertThat;
import static org.mockito.quality.Strictness.LENIENT;

@MockitoSettings(strictness = LENIENT)
public class JupiterTest {

   @InjectMocks
   private Jupiter jupiter;

   @BeforeEach
   public void setup() {
      //usually some stuff here
   }

   @Test
   @DisplayName("heading jupiter - make it so")
   public void test() {
      boolean result = jupiter.isAlpha();

      assertThat(result).isTrue();
   }
}

Not sure why need all that vintage and platform stuff.. Your tests are org.junit.jupiter.api.Test;

I would do this:

1) Remove all the annotations from the class level

2) Init Mockito:

@BeforeEach
public void setup() {
    MockitoAnnotations.initMocks(this);
}

3) These deps should be sufficient:

junit-jupiter 5.5.0
mockito-core 2.28.2
