java Junit4 and JUnit5 not picking JUnit5 tests

Question

I have a work environment including bom I dont manage and JUnit5 tests are not picked up unless I import my @Test annotation for test methods from import org.junit.Test; if I import them from import org.junit.jupiter.api.Test; they are not picked up by maven surefire plugin. I read in many parts and tested in a smaller project and its working and pickedup, I don't know what to include into this post so you have enough information to see where is the issue. Also if anybody can explain what is under the hood for the imports I read are needed for both JUnit 4 and 5 to work with surefire namely

    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-engine</artifactId>
        <version>${junit-jupiter.version}</version>
        <scope>test</scope>
    </dependency>
    <!--JUnit Jupiter Engine to depend on the JUnit4 engine and JUnit 4 API  -->
    <dependency>
        <groupId>org.junit.vintage</groupId>
        <artifactId>junit-vintage-engine</artifactId>
        <version>${junit-jupiter.version}</version>
    </dependency>

with versions

    <maven.surefire.version>3.0.0-M5</maven.surefire.version>
    <junit-jupiter.version>5.1.0</junit-jupiter.version>

I'd appreciate that.

Note that

• my tests are all under src/test/java/.....java
• methods are public
• methods start with test
• classes end with Test

Answer 1

Found that this dependency was conflicting, removing it solved my issue

    <dependency>
        <groupId>org.junit.platform</groupId>
        <artifactId>junit-platform-runner</artifactId>
        <version>1.8.2</version>
        <scope>test</scope>
    </dependency>

also updated spring-boot-dependencies version to 2.6.6, had issues with 2.3.3.RELEASE
