Maven Surefire 未运行 JUnit 5 测试

Question

I've been trying to run JUnit 5 tests with Maven Surefire. However, it doesn't seem like Surefire is running any tests at all, even though I do have some, and in the default directory, too.

This is the console output I'm getting: https://prnt.sc/ugo1xt

Here are the relevant parts of the pom.xml:

  <dependencies>
    <dependency>
       <groupId>org.junit.jupiter</groupId>
       <artifactId>junit-jupiter</artifactId>
       <version>5.7.0-M1</version>
       <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>${maven-surefire-plugin.version}</version>
      </plugin>
    </plugins>
  </build>

The surefire version is 3.0.0-M4.

I've tried pretty much any fix I could find on Google, although most of them seemed to be outdated. Any help would be greatly appreciated.

Cheers!

EDIT: Here's an example of my tests:

package bankprojekt;

import bankprojekt.verarbeitung.*;

import org.junit.jupiter.api.*;
import static org.junit.jupiter.api.Assertions.*;

public class GirokontoTest {
    Girokonto gk;

    @BeforeEach
    void setup(){
        gk = new Girokonto();
        gk.einzahlen(500);
    }

    @AfterEach
    void teardown(){
        gk = null;
    }

    @Test
    void abhebenMitWaehrungswechsel(){
        try{
            gk.abheben(195.583, Waehrung.BGN);
        }
        catch (Exception e) {
            System.out.println(e);
        }

        assertEquals(400, gk.getKontostand());
    }

    @Test
    void einzahlenMitWaehrungswechsel(){
        gk.einzahlen(195.583, Waehrung.BGN);

        assertEquals(600, gk.getKontostand());
    }
}

There are two things. First you should upgrade jacoco dependency to 0.8.5 otherwise it fails based on the JDK14 requirement. (Created an pull request to your repository). If those things are configured appropriately the result is this:

I would also recommend to upgrade maven-compiler-plugin to most recent version and also all other plugins.

As you can see you have WARNING's in your build which should be fixed and failing tests.

This build has been run on plain command line also with JUnit-Jupiter 5.7.0 which works perfectly.

I hit this strange error. No logs or traces shown.
